• Consider renaming 'UpdateLableCommand' to 'UpdateLabelCommand' to fix the typo and improve clarity.

package labels

pkg/api/label_handler.go:125

• If no label is found in GetLabelIdByName, returning 0 with err (which may be nil) could be misleading. Consider returning a clear error, such as 'label not found', to indicate the absence of a matching label.

		return 0, err

cmd/harbor/root/labels/delete.go:45

• [nitpick] Update the error message to clearly indicate that the failure occurred during retrieval of the label id for deletion, for example: 'failed to retrieve label id for deletion: %v'.

				return fmt.Errorf("failed to get label id: %v", err)
