I am following the example notebook as per GCP docs to test Vertex Matching Engine. I have deployed an index but while trying to query the index I am getting _InactiveRpcError. The VPC network is in us-west2 with private service access enabled and the Index is deployed in us-central1. My VPC network contains the pre-populated firewall rules.

Currently, Matching Engine only supports Query from the same region. Can you try running the code from VM in us-central1.
