I am working on a django project using python-social-auth to do authentication with facebook. I am running the django server on localhost and have facebook set up with my application to redirect to http://127.0.0.1:8000/complete/facebook/, which begins python-social-auth's pipeline to authenticate a user. I am using postgres as my database.
When this method is called and tries to authenticate, it cannot find information on the session. From https://github.com/omab/python-social-auth/issues/534 , I think the sessionid cookie is being overwritten. If I send the facebook redirect to a different url to load a static page without authentication, there is no error but I am also not authenticating or getting any information from facebook.
How would I go about not overwriting the sessionid cookie -if of course, that is the actual issue- or is there another problem that I might be missing here?

AuthStateMissing: Session value state missing.
This error was due to the session cookie not being saved over a non-https url. When testing on localhost with SESSION_COOKIE_SECURE set to True in django, the session cookies will not persist between redirect and you will get this error in any kind of page change where session would be checked.
SESSION_COOKIE_SECURE=False for testing and it's all good
