API Server logs:
Error on OAuth authorize: Could not build url for endpoint 'CustomAuthOAuthView.oauth_authorized' with values ['provider']. Did you mean 'CustomAuthOAuthView.logout' instead?

It worked in the previous version that I had installed (3.1.1)
What you think should happen instead?
Login should work
