error getting cluster: %q: %v

Error message

error getting cluster: %q: %v

What it means

RunCreateInstanceGroup loads the target cluster (e.g. via GetCluster) before building the IG spec; this wraps that lookup failing - typically the cluster does not exist, the state store is unreachable, or permissions are lacking.

Solutions

1. Verify the cluster name and that it exists in the state store
2. Check state store (S3/GCS) access and credentials
3. Create the cluster first if it does not yet exist
