I'm using python-social-auth to login with social networks from my Django application. On my local machine everything works fine, but when I deploy to a server I get the following error: 

oauthlib.oauth1.rfc5849.utils in escape
ValueError: Only unicode objects are escapable. Got None of type <type 'NoneType'>.

  • What version of Python are you using? I have a suspicion about what's causing this, but I'm not 100% certain. – Ian Stapleton Cordasco Sep 11 '14 at 12:14
  • @sigmavirus24 It's Python 2.7.6. In the same machine I have another Django project that uses ``python-social-auth`` and it works absolutely fine. – cansadadeserfeliz Sep 11 '14 at 12:33
  • I thought the difference might be in the `locale` settings but given you have a different app using it that is very curious. I'm not familiar with these projects to be helpful, but I'll point the maintainers of requests-oauthlib at this to see if they can help. – Ian Stapleton Cordasco Sep 11 '14 at 14:12
  • @sigmavirus24 Thank you for helping! I checked ``locale``and it's ``en_US.UTF-8``. Since both Django projects are running in the same server, they share the same ``locale``, but one project works well, and the other one not. – cansadadeserfeliz Sep 11 '14 at 14:26
  • Same problem, trying to upgrade t Django 1.7. Google suggests something is wrong with the variable name in the settings-file but of course, what the *correct* variable name is is of course not shown anywhere. – kaleissin Sep 20 '14 at 19:26

I got this error when I did not provide my OAuth Consumer key and secrets in my django settings file. It's essentially a "Required setting not found" error. Is it worth checking all your settings copied across successfully when you deployed?

I've upgraded to python-social-auth and had the same problem with Linkedin login. Parameter names in settings are changed in the latest version so instead: LINKEDIN_CONSUMER_KEY and LINKEDIN_CONSUMER_SECRET it'd be used: SOCIAL_AUTH_LINKEDIN_KEY and SOCIAL_AUTH_LINKEDIN_SECRET.

the problem comes to you if this statement have spelling mistake:

tweepy.OAuthHandler(consumer_key,consumer_secret)
