Launching Ray on GKE using Click to Deploy fails

[Shiti]

I've been trying to launch Ray on GKE using Google Click to Deploy Containers for Ray on GKE but it fails even when I try to use an existing cluster.

The form to launch, accepts Kubernetes cluster name, location, etc but I'm not sure if those are honored when the cluster is being launched, since it always shows the location as us-central-1.

Are there any additional steps that need to be taken in order to get this working?
