getting actual user-data: %w

Error message

getting actual user-data: %w

What it means

In checkUserDataDifferences, GetServerUserData('cloud-init') failed to fetch the server's current user-data, so it cannot be compared with the expected resource to decide whether the server needs an update. The wrapped error is the SDK response for that specific server.
