We have a setup with a few social connection and database connection.
While all social connections work fine when we try to sign up with login and password (database connection) we get login error and find this in Auth0 logs:
Unable to issue redirect for OAuth 2.0 transaction
I searched for possible reasons and in most cases the reason for this issue was that redirect_uri is not provided.
However in our case redirect_uri is set and also reported in the same log entry so I’m sure it’s reaching Auth0.
