The login Page doesn’t work when enabling only Social Connections, even though the Social connection is enabled. The following error appears:
error: invalid_request description: connection not found for the client
This is caused by the /authorize request having the parameter: screen_hint=“signup”. Given that there are only social connections enabled, no signups can be performed (They are just logins) so providing the screen_hint=“signup” param will cause this error.
Remove the screen_hint param from the /authorize request.
