Bug: identity.web.auth.get_user() return None even after getting token

[dcoe-jkpaper]

I'm using identity==0.9.2. I'm using below code to create login authentication for Microsoft. While using identity.web.auth.get_user() method to get the current login user info, I'm getting the None response from it. If I refresh the page after a few seconds, it works fine.

Code

from identity.web import Auth
AUTH = Auth(session=session, authority=secrets['ms_graph']['common']['AUTHORITY'], client_id=secrets['ms_graph'][location]['CLIENT_ID'], client_credential=secrets['ms_graph'][location]['CLIENT_SECRET'])
...

resp = AUTH.complete_log_in(request.args)

if "error" in resp:
    return redirect(f"/login_error")

result = AUTH.get_user()
location = result['preferred_username'].split("@")[1].split('.')[0]

I'm getting below error:

ERROR in app: Exception on /getAToken [GET]

Given that you seem using Flask, have you tried using a higher level API dedicated for Flask, which is also demonstrated in this completed sample? If that works for you, then just use it.

The from identity.web import Auth is now considered as a low level API which is trickier to get right. Is there any specific reason that you want to use it?

I'm closing this issue. The issue was with Nginx. It was not allowing cookies to be stored in the Flask session. I got it working.
