AttributeError: 'NoneType' object has no attribute 'split' #74

brandon-clair · 2018-03-15T20:20:42Z

I'm running Python 3.5 and Django 2.0.2.

After installing django-sslserver, I'm seeing an exception whenever there's any sort of POST to my localhost server. It doesn't yet seem to be causing any problems, but any advice would be appreciated.

Here's the traceback:

I'm currently running into the same issue too with a test application. Has anyone managed to identify the cause of this?

eavive · 2018-05-09T15:18:29Z

I see same errors with Python 3.5.2 + Django 2.0.3 on Ubuntu 16.04
When using Django 2.0.1 no errors appear.

Though I don't use django-sslserver at all.
Ended up here after searching Google for this error output.

I do use:
Django==2.0.3
django-extensions==2.0.5
django-filter==1.1.0
django-rest-framework-mongoengine==3.3.1
djangorestframework==3.7.7

gohanko · 2018-05-18T03:42:48Z

I think this might be an issue with django 2.0 itself, I noticed this error in 3 of my django project.

brandon-clair · 2018-05-19T04:04:29Z

tl;dr: pip install --force-reinstall requests[security] ...maybe

So I don't use this package anymore, but for those looking for a solution, the exception may be due to additional requirements in the requests package, and could potentially be solved by explicitly installing the requirements. It also seemed to help out over in a similar issue, but forcing a re-installation.

The exception certainly is coming from something outside of django-sslserver itself, so if anyone has success with the above, let us know so we could close this issue, with maybe just an update to requirements.txt.

AntJLopez · 2018-08-05T05:56:11Z

As suggested, I tried:
pip install --force-reinstall requests[security]

I am still experiencing the issue. Everything seems to be working properly, but the command line is flooded with these errors. It happens with every one of my Django projects.

I am using Python 3.7.0 and Django 2.1.

ssokolow · 2018-08-09T06:37:43Z

Judging by the traceback, this looks like the same error detailed in issue #31.

Note that the AttributeError is the result of a chain of During handling of the above exception, another exception occurred: lines.

Allan-Nava · 2018-08-28T08:59:17Z

How can I fix this problem?

captbilard · 2019-03-06T21:07:54Z

Am also having this issue now, and based on google search it seems like its a Django thing.
I created a form using ModelForm and when I try to save it to the DB. My console is flooded with the error message. I hope this is fixed soon.

abhishek-malik · 2019-04-03T21:54:08Z

I'm facing the same issue while working on windows and using firefox browser, whereas application is running fine on Ubuntu. Looks like there is some problem with the firewall processing the http requests.
This might help : wagtail/wagtail#4254

I had the same issue.
I solved it by setting DATA_UPLOAD_MAX_NUMBER_FIELDS = 10000 in settings.py
Django 2.2

Ontheroad123 · 2020-04-23T07:26:55Z

i have the same error,but i solve it .
I have built virtualenv:
python 3.6.0 ,old is 3.6.5
django 2.0.6,old is 2.2

ssokolow · 2020-04-23T07:30:53Z

@Ontheroad123 Are you saying that you downgraded Python and Django? ...because that's the worst thing you can do. You're testing against a version that you can't use in production because the whole point of newer versions is to fix known security vulnerabilities.

Might be related to this, probably fixed with Python 3.7.4+
