Exceptions and common tracebacks¶
Description
Common Python exception traceback patterns you may encounter when working with Plone and possible solutions for them.
Please see this tutorial for extracting Python tracebacks from your Plone logs.
Add-on installer error: This object was originally created by a product that is no longer installed¶
Traceback:
2009-10-18 13:11:20 ERROR Zope.SiteErrorLog 1255860680.760.514176531634 http://localhost:8080/twinapex/portal_quickinstaller/installProducts
Traceback (innermost last):

Module OFS.Uninstalled, line 40, in __getstate__
SystemError: This object was originally created by a product that
is no longer installed. It cannot be updated.
(<Salt at broken>)
Reason: Data.fs contains objects for which the code is not present. You have probably moved Data.fs or edited buildout.cfg.
Solution: Check that eggs and zcml contain all necessary products in buildout.cfg.
Add-on installer error: too many values to unpack¶
Traceback:

ValueError: too many values to unpack
Condition: When trying to install a plugin
Reason: You have run Data.fs with zope.component 3.5.1, but later downgraded / moved Data.fs.
Solution: Pin zope.component to 3.5.1.
Archetypes: TypeError: getattr(): attribute name must be string¶
Traceback:

AttributeError: appname
Possible reasons:
- You are using AnnotationStorage but you forgot to declare atapi.ATFieldProperty in your class body
- You are inhering schema in Archetypes, but you do not inherit the class itself
AttributeError: 'FilesystemResourceDirectory' object has no attribute 'absolute_url'¶
Traceback:

AttributeError: 'RelationList' object has no attribute 'source'
Reason: You're trying to use a relation field on your Dexterity-based content type but plone.app.relationfield is not installed.
Solution: Follow the instructions on the Dexterity documentation as relation support is no longer included by default.
AttributeError: 'module' object has no attribute 'HTTPSConnection'¶
Python has not been compiled with HTTPS support.
Try installing your Python, for example, using minitage.
See Python basics.
AttributeError: 'str' object has no attribute 'other' (Mixed zope.viewpagetemplate and Five.viewpagetemplate)¶
Traceback:

AttributeError: 'str' object has no attribute 'other'
Five ViewPageTemplate class file is slightly different than Zope 3's normal ViewPageTemplate file. In this case Five ViewPageTemplate was used, when Zope 3's normal ViewPageTemplate was expected.
Another reason is that acquisition chain is not properly set-up in your custom views.
Difference:
from Products.Five.browser.pagetemplatefile import ViewPageTemplateFile
vs.:
from zope.pagetemplate.pagetemplatefile import PageTemplateFile
AttributeError: 'wrapper_descriptor' object has no attribute 'im_func'¶

AttributeError: 'wrapper_descriptor' object has no attribute 'im_func'
Condition: This exception happens when starting Plone
Reason: You are trying to use Python 2.6 with Plone 3
Solution: With Plone 3 you need to use Python 2.4.
AttributeError: REQUEST in getObject¶
Traceback:

File "/srv/plone/saariselka/parts/zope2/lib/python/OFS/Traversable.py", line 259, in unrestrictedTraverse
next = queryMultiAdapter((obj, self.REQUEST),
AttributeError: REQUEST
Reason: You are using command line script. getObject() fails for a catalog brain, because the actual object is gone. However, unrestrictedTraverse() does not handle this case gracefully.
AttributeError: Schema¶
Traceback:

Module PythonExpr, line 1, in <expression>
Module AccessControl.ImplPython, line 675, in guarded_getattr
Condition: This error may comes when you try to view your custom content type
Reason: It is picking up Archetypes default view template for your Dexterity content type.
Try if you can access your view by a directly calling it to by its name. E.g.:
http://yoursite.com/folder/content/@@view
If it's working then it is wrong data in portal_types.
Your content item might also be corrupted. It is trying to use dynamic view selector even if it's not supported. Try re-creating the particular content item.

Module OFS.Traversable, line 64, in absolute_url
Module OFS.Traversable, line 117, in getPhysicalPath
AttributeError: getPhysicalPath
Another possible error is:
AttributeError: absolute_url
This usually means that you should have used context.aq_inner when you have used context. absolute_url() tries to get the path to the object, but object parent is set to view (context.aq_parent) instead of real container object (context.aq_inner.aq_parent).
Warning
When setting a member attribute in BrowserView, the acquisition parent of objects changes to BrowserView instance. All member attributes receive ImplicitAcquisitionWrapper automatically.
Demonstration
We try to set BrowserView member attribute defining_context to be some context object.:
(Pdb) self.defining_context = context
(Pdb) context.aq_parent
<PloneSite at /plone>
(Pdb) self.defining_context.aq_parent
<Products.Five.metaclass.HeaderAnimationHelper object at 0xadb5750>
(Pdb) self.defining_context.aq_inner.aq_parent
<Products.Five.metaclass.HeaderAnimationHelper object at 0xadb5750>
(Pdb) self.defining_context.aq_parent.aq_parent
<ATDocument at /plone/doc>
(Pdb) self.defining_context.aq_parent.aq_parent.aq_inner
<ATDocument at /plone/doc>
(Pdb) self.defining_context.aq_parent.aq_parent.aq_parent
<PloneSite at /plone>
To get the real object (as it was before set was called) you can create a helper getter:
def getDefiningContext(self):
"""
Un-fuse automatically injected view from the acquisition chain
@return: Real defining context object without bad acquistion
"""
if self.defining_context is not None:
return self.defining_context.aq_parent.aq_inner.aq_parent
return None

ContentProviderLookupError: plone.htmlhead
This is not a bug in Zope. It is caused by trying to
render a Plone page frame in an context which has not
acquisition chain properly set up. Plone
main_template.pt
tries to look up viewlet managers by acquistion traversing
to parent objects.
plone.htmlhead
is the first viewlet manager to be looked up like this,
and it will fail firstly.
Some possible causes:
-
You are trying to embed main_template inside form/view
which is already rendered in main_template frame. Please
see how to
embed forms and wrap forms manually. - You might be using wrong ViewPageTemplate import (Five vs. zope.pagetemplate - explained elsewhere in this documentation)
- Make sure that you call __of__() method for views and other objects you construct by hand which expects themselves to be in the acquisition chain (normally discovered by traversing)

Condition: When starting Zope
Reason: You probably have files lying over from wrong CPU architecture
- Hand copied eggs between servers

- You have several Python interpreters installed and you try to run Zope using the wrong interpreter (the one which the code is not compiled for)
Solution: Delete /parts and /eggs buildout folders, run bootstrap, run buildout.

ImportError: No module named html
Condition: This error can happen when starting an instance
Reason: The system lxml version is too old
Let's see if we are getting too old system wide lxml installation:
plone@mansikki:/srv/plone/yourinstance$ python2.4
Python 2.4.5 (#2, Jan 21 2010, 20:05:55)
[GCC 4.2.4 (Ubuntu 4.2.4-1ubuntu3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import lxml
>>> lxml.__file__
'/usr/lib/python2.4/site-packages/lxml/__init__.pyc'
>>> dir(lxml)
['__builtins__', '__doc__', '__file__', '__name__', '__path__']
>>> from lxml import html
Traceback (most recent call last):
File "<stdin>", line 1, in ?
ImportError: cannot import name html
If we cannot fix the system lxml (your system software depends on it) the only workaround is to create virtualenv. We cannot force Python 2.6, 2.5 or 2.4 not to use system libraries.
Example:
root@mansikki:/srv/plone# virtualenv -p /usr/bin/python2.4 --no-site-packages py24
Include standalone lxml + libxml compilation in your
buildout.cfg:
parts =
...
lxml
[lxml]
recipe = z3c.recipe.staticlxml
egg = lxml==2.2.6
force = false
If there are exiting lxml builds in buildout be sure they are removed:
rm -rf eggs/lxml*
Then as the non-root re-bootstrap the buildout using non-system wide Python:
plone@mansikki:/srv/plone/yourinstance-2010/yourinstance$ source /srv/plone/py24/bin/activate
(py24)plone@mansikki:/srv/plone/yourinstance-2010/yourinstance$ python bootstrap.py
...
(py24)plone@mansikki:/srv/plone/yourinstance-2010/yourinstance$ bin/buildout
...
... and after this it should no longer pull the bad system lxml.

Condition: This exception can happen during Plone migration to the newer version
It is caused by a property (site setting) which already exists and migration tries to create it. The usual reason is that one has edited site settings in new Plone version before running the migration.
Try remove violating property ids from the site_properties manually in Zope.
Potential candidates to be removed:
- enable_inline_editing
- lock_on_ttw_edit (boolean)
Potential candidates which need to be added manually:
- redirect_links (boolean)

notice the 'Could not import class' message.
Reason: You do not have identical product configuration on the new server. Please install the missing products and site should work fine again.
Please note that you can get a 'TypeError: iteration over non-sequence' exception in other contexts not related with missing products at all. Look for the 'Could not import class' message in your traceback.

TypeError: iteration over non-sequence
Reason: You are trying to use Plone 4 (Zope 2.12) add-on on Plone 3 (Zope 2.10). Zope interface declarations have been changed.
Solution 1: Pick the older version for
the add-on which is known to work with Plone 3. Make
sure that you delete all "too eggs" from
eggs/
and
src/
folders.
Solution 2: Upgrade your site to Plone.

This seems to be Plone 4 issue of some sort. Import Products.ATContentTypes before importing LinguagePlone.
NameError: name 'test' is not defined¶
Condition: This exception occurs when you try to customize TAL page template code using test() function. test() function has been dropped in Zope 3 page templates. You should no longer use test() function anywhere.
Solution: replace test() with common Python expression in your customized template.
For example the orignal:
tal:attributes="class python:test(here.Format() in ('text/structured', 'text/x-rst', ), 'stx' + kss_class, 'plain', + kss_class)"
would need to be written as:
tal:attributes="class python:here.Format() in ('text/structured', 'text/x-rst', ) and 'stx' + kss_class or 'plain' + kss_class"
NotFound error (Page not found) when accessing @@manage-portlets¶
If you get Page not found error when accessing @@manage-portlets the first thing you need to do is to enable logging of NotFound exceptions in ZMI in error_log.
After that reload @@manage-portlets.
When you try to access @@manage-portlets an exception a NotFound exception is raised:

NotFound: collective.easytemplate.TemplatedPortlet
This usually means that your site has an portlet assignment which code is not present anymore.
In this case you can see that portlet type "collective.easytemplate.TemplatedPortlet" is missing.
Ä Check that you include the corresponding product (collective.easytemplate) in eggs= section in buildout.cfg
- Reinstall removed egg which has the code for the portlet
- Check that you include the corresponding product (collective.easytemplate) in zcml= section in buildout.cfg
- Make sure that portlet name is the same in ZCML and GenericSetup XML
- Make sure you use <include package=".portlets" /> in your code

It usually means that there is a portlet in your content which product code has been removed.
Reinstall the add-on providing the portlet, remove the portlet and then uninstall the add-on again.
NotFound while accessing a BrowserView based view¶
Traceback:
Traceback (innermost last):
Module ZPublisher.Publish, line 110, in publish
Module ZPublisher.BaseRequest, line 506, in traverse
Module ZPublisher.HTTPResponse, line 686, in debugError
NotFound: <h2>Site Error</h2>
Condition: You'll get a NotFound error when accessing view using view traverse notation, event though the view exist.
Example URL:
http://yoursite/@@myview
Reason: This is because there is an exception raised in your view's __init__() method. Views are Zope multi-adapters. Exception in multi-adapter factory method causes ComponentLookUpError. Zope 2 publisher translates this to NotFound error.
Solution: * Put pdb break statement to the beginning of the __init__() method of your view. Then step through view code to see where the exception is raisen. * If your view does not have __init__() method, then copy the source code __init__() method to your view class from the first parent class which has a view
POSKeyError¶
POSKeyError is when the database has been unable to convert a reference to an object into the object itself It's a low level error usually caused by a corrupt or incomplete database.
- You did not copy blobs when you copied Data.fs
- Your data is corrupted
- Glitch in database (very unlikely)
PicklingError: Can't pickle <class 'collective.singing.async.IQueue'>: import of module collective.singing.async¶
Singing & Dancing add-on does not uninstall cleanly. Try this command-line script to get it fixed (not tested). Some parts may work, some not, depending on how messed up your site is.
Note that you need to have S & D present in the buildout when running this and then you can remove it afterwards:
import transaction
from collective.singing.interfaces import ISalt
from collective.singing.async import IQueue
# Your site here
portal = app.mfabrik
sm = portal.getSiteManager()
util_obj = sm.getUtility(ISalt)
sm.unregisterUtility(provided=ISalt)
del util_obj
sm.utilities.unsubscribe((), ISalt)
del sm.utilities.__dict__['_provided'][ISalt]
del sm.utilities._subscribers[0][ISalt]
util = sm.queryUtility(IQueue, name='collective.dancing.jobs')
sm.unregisterUtility(util, IQueue, name='collective.dancing.jobs')
del util
del sm.utilities._subscribers[0][IQueue]

RuntimeError: maximum recursion depth exceeded
Condition: The following code will generate this error when you try to access the object:
atapi.ImageField(
'memberimage',
# storage=atapi.AnnotationStorage(), # paster version
storage=atapi.AttributeStorage(), # results in "max recursion depth exceeded" error
widget=atapi.ImageWidget(
label=_(u"New Field"),
description=_(u"Field description"),
),
validators=('isNonEmptyFile'),
original_size=(600,600),
sizes={ 'mini' : (80,80),
'normal' : (200,200),
'big' : (300,300),
'maxi' : (500,500)},
),
Reason: Schema fields using AttributeStorage (usually images, files) cannot have ATFieldProperty in the class:
class Sample(base.ATCTContent):
# This does not work with AttributeStorage
memberimage = atapi.ATFieldProperty('memberimage')
Solution: simply remove ATFieldProperty() declaration for the problematic field. You cannot access the field value anymore by calling object.memberimage but you need to call object.getMemberimage() instead.

Reason: From line
Products/PageTemplates/Expressions.py
you can see the error comes from TAL templates. TAL
templates are trying to execute path based expressions.
If you can view this error through error_log the error_log traceback will contain information what expression causes the exception. However if this only happens with unit tests you can have something like:
def __call__(self, econtext):
if self._name == 'exists':
return self._exists(econtext)
print "Evaluating expression:" + self._s
return self._eval(econtext)
manually injected to
zope.tales.expression
module.

Unknown message (kss optimized for production mode) in Javascript console¶
This is a KSS error message. KSS is an technology used in Plone 3 and started to be phased out in Plone 4.
Possible causes:
- Problems with KSS files (see portal_kss registry)
- Browser bugs (Google around for the fixes)
Solution:
- Go to portal_kss
- Remove are stale entries (missing files, marked on red)
Also:
- Put portal_kss for debug mode (in development environment)

Zope suddenly dies on OSX without a reason¶
Symptoms: you do a HTTP request to a Plone site running OSX. Zope quits without a reason.
Reason: Infinite recursion is not properly handled by Python on OSX. This is because OSX C stack size is smaller than Python default stack size. The underlying Python interpreter dies before being able to raise stack size limit exception.
Solution
Edit
python-2.4/lib/python2.4/site.py
or corresponding Python interpreter
site.py
file (Python site installation customization file).
Put in to the first code line:
sys.setrecursionlimit(800)
This will force smaller Python stack not exceeding native OSX C stack. You might want to test other values and report back the findings.

z3c.form based form updateWidgets() raises ComponentLookupError¶
Case 1: z3c.form with Plone 3¶
Traceback:

raise ComponentLookupError(objects, interface, name)
ComponentLookupError: ((<Products.Five.metaclass.documentoverriderform object at 0x711c6f0>, <HTTPRequest, URL=http://nohost>, <ATDocument at /plone/doc>), <InterfaceClass z3c.form.interfaces.IWidgets>, u'')
Reason: To use z3c.form based forms z3c.form.interfaces.IFormRequest must be enabled for HTTP request object to make form layer adaptions work.
Solution:
- Wrap your forms with plone.z3cform.layout.wrap_form() call as instructed in plone.z3cform README
The same error occurs if plone.app.z3cform, plone.z3cform and z3c.form are not properly included through ZCML. In order to be sure that those modules are properly included, you can add the following lines into your configure.zcml
<include package="plone.app.z3cform" />
<include package="plone.z3cform" />
<include package="z3c.form" />
...or you can use autoinclude feature for Plone 3.3+
in configure.zcml
<includeDependencies package="." />
and then your add-on product setup.py file:
install_requires=[
'setuptools',
'plone.app.z3cform',
# -*- Extra requirements: -*-
],
Also remember to run Plone add-on installer for plone.app.z3cform (though it is unrelated to this error).
Case 2: missing plone.app.z3cform migration¶

Reason: You are running Plone 4 with
plone.app.directives
form which does not open. The reason is that you most
likely have old
plone.app.z3cform
installation which is not upgraded properly. In
particular, the following layer is missing
<layer name="plone.app.z3cform" interface="plone.app.z3cform.interfaces.IPloneFormLayer" />
This enables
z3c.form
widgets on a Plone site.
Solution: portal_setup > Import. Choose profile Plone z3cform support. and import. The layer gets properly inserted to your site database.
