Maybe not related to fandjango: user.oauth_token.extend() fails very often

[Morpho]

About 10% of the requests generated by user.oauth_token.extend() fail. I have no clue why exactly they fail. Facebook returns the following:
response = {u'error_code': 1, u'error_msg': u'An unknown error occurred'}

So in models.py line 256 an AttributeError exception is raised, because it cannot parse the response.

1. components = parse_qs(response)

Do you guys have any clue why Facebook returns that error?

Hi @Morpho,

I haven't had the opportunity to run the latest version in production yet. Have you enabled the migration in your application's settings on Facebook?

[Morpho]

Yes everything is enabled. I am using the newest version of the Facebook API, so no more "offline access", new auth dialog, etc. Its just weird that it only fails sometimes, without any reason. I will look further into it and let you know here. Besides of that, your code is VERY stable and runs without any exceptions. I really love it!

Thanks!

If the issue persists, we might consider to catch and ignore the exception until Facebook sorts it out (presuming it's a bug on their side, which seems likely).

And here's a stacktrace:

AttributeError: 'dict' object has no attribute 'split'

Thanks guys. I've made some configurations to ignore exceptions raised by extend until Facebook resolves this issue.

$ pip install fandjango --upgrade
