• Python social auth: 0.2.1

• Facebook app: v2.2

• Since: March 28, 2017 (as v2.2 was deprecated on March 27). Updated the Facebook App to latest, but the error persists.

Does the latest python-social-auth work? (0.3.6)

[scottlinux]

Try python-social-auth==0.2.21

I was unable to upgrade to latest. However, upgrading to 0.2.19 worked and also solved this issue.
