Problem
Getting
redirect_uri_mismatcherror from Google OAuth because:https://sales-agent.scope3.com/admin/auth/google/callbackhttps://sales-agent.scope3.com/auth/google/callback(missing/admin)The issue is that nginx routes all admin UI traffic through
/admin/*but Flask doesn't know about this prefix.Solution
Auto-detect and add
/adminprefix to the OAuth redirect URI whenGOOGLE_OAUTH_REDIRECT_URIenvironment variable is not set.Changes
/adminprefix/auth/google/callback→/admin/auth/google/callbackGOOGLE_OAUTH_REDIRECT_URIenv var if setTesting
The redirect URI should now match Google OAuth credentials:
https://sales-agent.scope3.com/admin/auth/google/callback/adminprefix to match nginx routingCheck logs for:
OAuth redirect URI: ...to verify correct URL is being used.
