Hi @ivo.pachecu,
Thank you for your response.
After reviewing your Action script, it looks like you need to resume authentication after the redirect to the /continue endpoint. If this step is skipped, Auth0 will lose the context of the login transaction, and the user will not be able to log in due to an invalid_request error.
See here to learn more about resuming the authentication flow after a redirect.
Please let me know if you have any questions.
Thank you.
