We’re using Classic Universal Login with passwordless only and magic link emails.
Clicking on the email link logins successfully on Auth0 and our callback is called with two params - ‘state’ and ‘code’.
Our callback is using Python + Flask
However, when during the callback processing it fails with:
authlib.common.errors.AuthlibBaseError: invalid_request: Invalid redirect_uri. Expected type ‘string’ but found type undefined
Auth0 Logs is showing a “Failed Exchange” type error.
I’m sure we are doing something obviously wrong - its just not that obvious to me!
Has anyone else experienced this error?
