waiting for route table deletion completion: %w

What it means

Wrapped error from future.PollUntilDone while waiting for a route table DELETE to complete. The delete operation started but finished with failure or the polling context was cancelled before completion.

Solutions

1. Read the wrapped error for the ARM delete failure reason
2. Remove any resource locks or subnet associations blocking deletion
3. Increase the polling context timeout
4. Verify deletion state in the portal; re-run delete if it is stuck

ctx, cancel := context.WithTimeout(ctx, 5*time.Minute)
defer cancel()

var respErr *azcore.ResponseError
if errors.As(err, &respErr) {
	// Conflict/InUseErrorCode indicates association still present
}

err := client.Delete(ctx, rg, name)
if err != nil {
	var respErr *azcore.ResponseError
	if errors.As(err, &respErr) && (respErr.StatusCode == 429 || respErr.StatusCode >= 500) {
		return retryWithBackoff(ctx, func() error { return client.Delete(ctx, rg, name) })
	}
	return err
}

When it happens

Trigger: PollUntilDone(ctx, nil) returns error when the ARM DELETE operation reports failure (e.g., resource locked, association conflict) or ctx is cancelled/timed out during polling.

Common situations: Route table still associated with subnets in another operation's scope; Azure ResourceManager locks on the resource group; short context deadline against slow deletes.
