  "error": {
    "code": 401,
    "message": "Request had invalid authentication credentials. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.",
    "status": "UNAUTHENTICATED"
  }
}

Answer 1

It could be that The Application Default Credentials are not available

Try to login by running

gcloud auth application-default login

And follow the instructions, reference: gcloud auth application-default login

If you want to make sure the authentication process went well, run:

gcloud auth application-default print-access-token

You should see an access token, reference gcloud auth application-default print-access-token

Answer 2

Replace $(gcloud auth application-default print-access-token) with what gets printed when you call the command.

Answer 3

I fixed the problem by logging out, and logging in to agree to some new terms and conditions google have made since last time I used google clouds (firebase in my case).
