Error returning OAuth user info: missing_token due to AuthLib V1.0.0

[JZ6]

The latest AuthLib breaks Oauth, returns the "Error returning OAuth user info: missing_token".
Downgrading back to authlib==0.15.5 fixes this error and allows SSO to work again.

How to reproduce the bug

1. Setup Google Oauth
2. Install Authlib 1.0.0
3. Try to login
4. See Error returning OAuth user info: missing_token

Expected results

Login via google SSO keeps working.

Actual results

Latest AuthLib releases throws a missing_token error.

Is this still an issue on 2.0.1?

I have tested this again. It does not seem to be an issue anymore. Just note that it does not work if using:
'server_metadata_url': 'https://accounts.google.com/.well-known/openid-configuration',

The URLs have to be manually defined.
