- Updated `kubectl scale` to return a consistent error message when a specified resource is not found. Previously, it returned: `error: no objects passed to scale <GroupResource> "<ResourceName>" not found`. It now matches the format used by other commands (e.g., `kubectl get`): `Error from server (NotFound): <GroupResource> "<ResourceName>" not found`.

For instance, a function to read data from a file might be declared:
