I noticed this error while trying to access /admin/. Whenever /admin/model_name or /admin/ or /admin/* is accessed django says OverflowError at /admin/ and regular expression code size limit exceeded. I did a little digging and came across this SO post. I have checked urls.py of app since regex are mostly used in urls. But all I have is a typical admin url, nothing complex.
from django.contrib import admin
urlpatterns = [
url(r'^admin/', admin.site.urls),
....
]

We are using django+apache.
Any help is much appreciated.
TIA
I have managed to solve this by restarting apache2 with
sudo service apache2 restart.
Of course, I have inspected apache2 error log with
sudo tail-f /var/logs/apache2/error.log
But that gave me same output as stack trace. Aforementioned is a work around for this issue. I am not marking this question as solved since real issue have not been found yet.
Thanks.

I am trying to implement a google login onto my project. I already had a relatively working login scheme when I tried to use social_core's oauth with google to log in with a google account. It keeps throwing a social_core.exceptions.AuthMissingParameter error, meaning that somehow, the state isn't being passed at all.
I have been following the walkthrough done here https://fosstack.com/how-to-add-google-authentication-in-django/ as a baseline for how to implement this. When I run the code from this tutorial (besides some basic syntax and version errors), everything runs like a charm. However, when I try to implement it on my project, an error I cannot resolve occurs.
The url.py file I have, I have only imported some files and added the line
path('auth/', include('social_django.urls', namespace='social')),
Other, than that, most of my test code is similar to the blog: like this in my common file.
AUTHENTICATION_BACKENDS = (
'social_core.backends.open_id.OpenIdAuth', # for Google authentication
'social_core.backends.google.GoogleOpenId', # for Google authentication
'social_core.backends.google.GoogleOAuth2', # for Google authentication
'django.contrib.auth.backends.ModelBackend',
)
How the current situation is, is that I can click login, it takes me to a login page where I type in my google account, and then it throws the following exception:

Where I have edited out some of the more personal information, but those files aren't being used currently. I am pretty sure I have my keys done correctly, because the parameters are correct when I print them in the terminal after I run the server, and for the fact that google manages to send me the redirect at all.
Edit: Pretty sure the keys are correct, since when I remove them or type them incorrectly, I get a server not found error rather than a missing parameter error.
I'm getting NoReverseMatch from the below view:
from django.shortcuts import render, redirect
def new_room(request):
label="test"
return redirect(chat_room, label=label)
# this didn't work either:
# return redirect('chat_room', label=label)
def chat_room(request, label):
...
My urls.py looks like this:
from django.conf.urls import url, include
from messaging import views
app_name="messaging"
urlpatterns = [
url(r'^$', views.index, name='index'),
url(r'^new/$', views.new_room, name='new_room'),
url(r'^(?P<label>[\w-]{,50})/', views.chat_room, name='chat_room'),
]
Going straight to messaging/test/ will load the page correctly. It's only the redirect that is causing the issue.

That's because you're using namespacing for your chat_room app.
Change to:
return redirect('messaging:chat_room', label=label)
Check here for namespacing and also here too.

I have this function working in another project without problems...
I got exactly this same message when I accidentally used the messages framework incorrectly in the form_valid method of a completely different view in my project.
The correct code should have been:
messages.success(request, "Deactivated product")
But what I had written instead was
messages.success = "Deactivated product"
This code doesn't work, but it doesn't cause an error on the page, either! However, as soon as I submitted a different form that used the SuccessMessageMixin, I would see the 'str' object is not callable error.
(Having a problem on one page cause an error on a completely different page was fun to debug.)

Its hard to tell but somewhere, either in urls.py and views.py are matches you should check the type of object being passed. It may not have expected value.
For instance /jobs/1/match, 1 maybe expected to be int but turns out be be str.
maybe because the text is being entered as unicode, try key.encode.('UTF-8')
