Installation Method

git clone

Environment

Open WebUI Version: dev branch in commit 0425621494

Confirmation:

I have read and followed all the instructions provided in the README.md.

Description

At oauth.py#L203, the program directly indexes the key userinfo from the token and later checks if not user_data:.
The issue here is that if the OAuth provider does not provide the 'userinfo' field (for example, GitHub only provides access_token), the program will not proceed to the next step but will instead crash, displaying an internal error on the webpage.
The fix is to modify it to:

user_data: UserInfo = token.get("userinfo")
