我正在尝试通过自定义分类法创建一个自定义端点，我已经为这些类别创建了另一个端点，它工作得很好，但是有一些问题我无法解决

function get_latest_posts_by_term($request) {

    $args = array(
            \'term\' => $request[\'term_id\']
    );

    $posts = get_posts($args);
    if (empty($posts)) {
    return new WP_Error( \'empty_term\', \'There are no posts to display\', array(\'status\' => 404) );

    }

    $response = new WP_REST_Response($posts);
    $response->set_status(200);

          $data = [];
          $i = 0;

    foreach($posts as $post) {
        $data[$i][\'id\'] = $post->ID;
        $data[$i][\'title\'] = $post->post_title;
        $data[$i][\'excerpt\'] = $post->post_excerpt;
        $data[$i][\'date\'] = $post->post_date;
        $data[$i][\'content\'] = $post->post_content;
        $data[$i][\'slug\'] = $post->post_name;
        $data[$i][\'author\'] = get_the_author_meta(\'display_name\', $post->post_author);
        $data[$i][\'category\'] = get_the_category( $post->ID);  
        $data[$i][\'theme\'] = get_the_terms($post->ID,\'theme\');
        $data[$i][\'Rute-geografic\'] = get_the_terms($post->ID,\'rute-geografice\');
        $data[$i][\'featured_image\'][\'thumbnail\'] = get_the_post_thumbnail_url($post->ID, \'thumbnail\');
        
        $data[$i][\'post_tags\'] = get_the_terms($post->ID,\'post_tag\');
        
        
        
        $i++;
    }

    return $data;
}

add_action(\'rest_api_init\', function() {
register_rest_route( \'wl/v1\', \'posts/term/(?P<term_id>\\d+)\',array(
                \'methods\'  => \'GET\',
                \'callback\' => \'get_latest_posts_by_term\'
      ));
    
});
