It seems like get_input('guid') can also be of type string; however, parameter $guid of get_entity() does only seem to accept integer, maybe add an additional type check?

		if (!$entity) {
			return;
		}
		
		$response->getData()->likes_status = [
			'guid' => $entity->guid,
			'count' => likes_count($entity),
			'count_menu_item' => elgg_view_menu_item(_likes_count_menu_item($entity)),
			'like_menu_item' => elgg_view_menu_item(_likes_menu_item($entity)),
			'is_liked' => DataService::instance()->currentUserLikesEntity($entity->guid),
		];
		
		return $response;
