Do you have the install completed correctly? It appears that the credentials are not found. Are you running inside docker or does some other user have access to the credentials file? Have you installed the Oauth file correctly?

Most likely this is because of your client_secret file. You probably are missing
"redirect_uris": ["https://****.firebaseapp.com/__/auth/handler"]
`

If you open your client secret file, add this before client_secret. To get the URL, You can try localhost, however you may need to go to OAth and look at the original key that was created. It should have the URLs in it
