StatusCode_DEPLOY_CLOUD_RUN_DELETE_WORKER_POOL_ERR

Error message

unable to delete Cloud Run WorkerPool

What it means

Thrown by deleteRunWorkerPool when the WorkerPools API delete call (crclient.Namespaces.Workerpools.Delete(sName).Do()) fails. Resource name construction succeeded, but the API returned an error, which is embedded verbatim in the actionable error message.

Solutions

1. Check the embedded API error: 404 means nothing to delete — safe to continue
2. Ensure the Cloud Run Worker Pool API is enabled and the caller has delete permissions (roles/run.admin)
3. Confirm the project and workerpool name in the constructed resource name are correct
4. Retry transient 5xx/network failures with backoff

call := crclient.Namespaces.Workerpools.Get(sName)
if _, err := call.Do(); err != nil {
	if gErr, ok := err.(*googleapi.Error); ok && gErr.Code == 404 {
		return nil // already gone
	}
	return err
}

if _, err := delCall.Do(); err != nil {
	var gErr *googleapi.Error
	if errors.As(err, &gErr) {
		switch {
		case gErr.Code == 404:
			return nil // idempotent
		case gErr.Code == 403:
			return fmt.Errorf("missing WorkerPool delete permission / API not enabled: %w", err)
		case gErr.Code == 429 || gErr.Code >= 500:
			return retryWithBackoff(delCall)
		}
	}
	return err
}

When it happens

Trigger: cleanupRun -> deleteRunWorkerPool calls Namespaces.Workerpools.Delete on namespaces/<proj>/workerpools/<name> and the API returns non-2xx or a transport error.

Common situations: WorkerPool already deleted or never created (404); missing IAM permission for the (alpha) WorkerPool API; WorkerPool API not enabled/available in the project or region; transient network failures.
