error waiting for Network creation to complete: %w

Error message

error waiting for Network creation to complete: %w

What it means

Wrapped error from cloud.WaitForOp after a successful Networks.Insert submit. The network-create operation failed asynchronously (or polling errored) — e.g. legacy CIDR conflicts with an existing peered network, so the network may not exist despite the accepted request.

Solutions

1. Read the operation error detail in the %w chain
2. Verify whether the network was created (gcloud compute networks describe)
3. Fix the underlying cause (CIDR overlap, quotas) and re-run the apply
