When I try to login into my discourse setup using SSO, i get the following error : - **Error updating information, contact site admin discourse** This is what I am getting in error logs, ``` Job exception: undefined method `length' for nil:NilClass ``` What could have possibly caused this ? am on _ **v1.3.0.beta6 +223** _ ---

Which provider did you use? One of my users reported issues with GitHub earlier today (which I was able to replicate) but within minutes it appears to have fixed itself. ---

@limeblast I’ve setup discourse on my local machine, using ubuntu 14.04. SSO integration is done with one other site. It was working fine for 2 months, this issue has come up very recently, i got to know about it today. ---

Can you provide a deeper stack trace from the logs? ---
