The gcloud scheduler HTTP task fails for lack of authentication
I'm trying to use the http string in the gcloud task scheduler from https://cloud.google.com/compute/docs/reference/rest/v1/instances/start
So my string looks like https://www.googleapis.com/compute/v1/projects//zones/europe-west2-c/instances//start?key=
But it keeps failing authorization.
However if I execute this string from the web-link above with the Google OAuth2 it works.
