Beginning to use pulumi om GKE. and i manage to create a cluster, but when i want to make a namespace it cannot find my credentials.

Attempted to load application default credentials since neither `credentials` nor `access_token` was set in the provider block.  No credentials loaded. To use your gcloud credentials, run 'gcloud auth application-default login'.  Original error: google: could not find default credentials. See <https://developers.google.com/accounts/docs/application-default-credentials> for more information.

i have the GOOGLE_CREDENTIALS env var loaded, i assumed i would not need to run gcloud commands to make this work?
