fced3ef fix: Trailing slash was never removed from request.base_url because it's not a string but rather a starlette.datastructures.URL

📄 Description

Summary

Convert the value used to build the OAuth callback redirect URL to a plain string so that a trailing slash can be trimmed correctly. This prevents the generated redirect from containing two slashes (e.g. https://host//auth) which breaks login when Azure AD / Microsoft OAuth is used.

Background

backend/open_webui/utils/oauth.py constructs the post-login redirect like this:

redirect_base_url = request.app.state.config.WEBUI_URL or request.base_url
if isinstance(redirect_base_url, str) and redirect_base_url.endswith('/'):
    redirect_base_url = redirect_base_url[:-1]
redirect_url = f"{redirect_base_url}/auth#token={jwt_token}"

request.base_url is a starlette.datastructures.URL object, not a str. When WEBUI_URL is unset and the code falls back to request.base_url, the isinstance(..., str) check fails, so the trailing slash is not removed. After implicit string conversion we end up with ...//auth.
