custom-metrics-stackdriver-adapter not working - auth problems?

Hi have created a new GCP project and a GKE cluster inside it.

I've followed the instructions in the [README](https://github.com/GoogleCloudPlatform/k8s-stackdriver/blob/master/custom-metrics-stackdriver-adapter/README.md)...

However Logs Explorer is complaining about it... looks like an authentication problem?
