error waiting for Subnet creation to complete: %w

Error message

error waiting for Subnet creation to complete: %w

What it means

Wrapped error from cloud.WaitForOp after a successful Subnetworks.Insert submit. The subnet-create operation failed asynchronously (or polling errored) — the subnet may not exist even though the request was accepted; the %w carries the operation-level failure.

Solutions

1. Inspect the operation error in the %w chain
2. Check whether the subnet exists (gcloud compute networks subnets describe) before retrying
3. Fix the underlying cause (overlap, quota) and re-run the apply
