error parsing network name from cluster spec: %w

Error message

error parsing network name from cluster spec: %w

What it means

Wrapped error from Subnet.Find when gce.ParseNameAndProjectFromNetworkID cannot parse the cluster spec's Networking.NetworkID into a network URL. The %w carries the parse error — the NetworkID field holds a malformed value, so the subnet lookup cannot determine which project to query.

Solutions

1. Fix Networking.NetworkID in the cluster spec to a valid network name or full network self-link URL
2. Check the wrapped parse error for the expected format
3. Run kops edit cluster and re-apply
