The redirect URI in the request: https://auth.firebase.com/auth/google/callback does not match the registered redirect URI. "

I tried to fill in both of the following redirect URIs in google client id

    https://auth.firebase.com/v2/saas/auth/google/callback/    ('saas' is my firebase name)
    https://auth.firebase.com/auth/google/callback

Origin of Javascript

    https://auth.firebase.com
