I'm trying to add a GCP monitor, but it is 'discovering' for hours. ("Your GCP resources are being discovered, this may take a while."  keeps being displayed).  In 2nd browser window I can see that it has disovered a Kubernetes cluster, but that's all. No VM Instances/disks/storage/etc.  And the only information it gathered from the GKE cluster is the configuration details.  All other information (CPU usage/disk etc is empty). Also no information on what is running within the cluster.

I've also tried to install the metrics agent (not sure if this is needed for getting even basic information on the cluster), and although the metrics pod is running, it is flooding the logs with :

Failed to list *v1beta1.ReplicaSet: the server could not find the requested resource

(we're running 1.19.9-gke.100)

The service account I've setup does have the required Viewer role, so not sure what else to do to get this discovery (of i.e. VMs and storage etc outside of the K8S cluster) working.
