Getting an exception/error when people cancel partway through authentication

[Tobe Nwanna]

So I'm currently using the facebook and google-oauth2 backends for my site and when people are redirected and click cancel I want them to go back to my site but instead they simply see an error message (well a 500 on the production site). I entered in a value for SOCIAL_AUTH_LOGIN_ERROR_URL to handle this but it doesn't seem to be redirecting there. Maybe I'm handling this case incorrectly?

Add this middleware[1] to your middlewares setting, it will redirect any social
related exception to SOCIAL_AUTH_LOGIN_ERROR_URL which two query parameters,
message (exception message) and backend name (backend being used during the
process).

I have both of those but it still doesn't seem to be working...it's going to this page /complete/backend_name instead of what I specified
