Expected Behavior

We expected terraform to be able to create the nodepool with associated network configuration

Actual Behavior

Terraform returned an error saying node_network_config.pod_range is not a valid GCP resource name where the value we provided is pod_range_prow (name we want to use to define the pod range).
Note that I am able to create the node pool with the same configuration through GCP UI

Steps to Reproduce

1. terraform apply

Found out the issue is pod_range cannot contain underscore character, I replaced with hyphen and it works 👍
