Ошибка при пагинации. ругается на переменную count в movies.php. в чем может быть ошибка?

public function type($slug=NULL)
		{
			$this->load->library('pagination');

			$this->data['movie_data'] = NULL;

			$offset = (int)$this->uri->segment(4);
			
			$row_count = 2;

			$count = 0;

			if ($slug == 'films') {
				$count = count($this->films_model->getFilms(0, 1)); //Ругается на эту строку: count(): Argument #1 ($var) must be of type Countable|array, null given
				$p_config['base_url'] = 'movies/type/films/';
				$this->data['title'] = 'Фильмы';
				$this->data['movie_data'] = $this->films_model->getMoviesOnPage($row_count, $offset, 1);
			}

			if ($slug == 'serials') {
				$count = count($this->films_model->getFilms(0, 2));
				$p_config['base_url'] = 'movies/type/serials/';
				$this->data['title'] = 'Сериалы';
				$this->data['movie_data'] = $this->films_model->getMoviesOnPage($row_count, $offset, 2);
			}

			
			if ($this->data['movie_data'] == NULL) {
				show_404();
			}

			//Pagination code
			$p_config['base_rows'] = $count;
			$p_config['per_page'] = $row_count;

			//Init pagination
			$this->pagination->initialize($p_config);

			$this->data['pagination'] = $this->pagination->create_links();

			$this->load->view('templates/header', $this->data);
			$this->load->view('movies/type', $this->data);
			$this->load->view('templates/footer');
