Sorry for so late response Carlos, I didn’t see a notification.
The exact steps to reproduce the issue:
- Navigate to hosted login page from the client site
- Login or signup. After that user is redirected to
redirect_uri (back to the client site)
- press browser back button and try to login or signup
- An error occurs and a custom error page is showed with missing
client_id query param
Error would be the following: Password login via OIDC-conformant clients with externally-hosted login pages is unsupported. Alternatively, login could have been initiated from the wrong place (e.g., a bookmark).
Thanks in advance
