我很难使用REST API获取一些自定义的post类型。我收到404信息，但所有设置都正确。有解决方案吗？

<div class="row services-content">
<?php $services = new WP_Query( [\'post_type\' => \'servizi\'] ); ?>
<?php if( wp_is_mobile() ): ?>
  <div class="col-sm-12 text-center" style="padding:0;">
    <div class="swiper-container services-carousel">
      <div class="swiper-wrapper">
      <?php if( $services->have_posts() ): while( $services->have_posts() ): $services->the_post(); ?>
        <div class="swiper-slide" style="background-image:url(\'<?php echo the_post_thumbnail_url(); ?>\');">
        <h4 class="service-slide-name"><?php the_title(); ?></h4>
        </div>
      <?php endwhile; ?>
      <?php endif; wp_reset_postdata(); ?>
      </div>
      <!-- Pagination -->
      <div class="swiper-pagination"></div>
      <!-- Arrows -->
      <div class="swiper-button-next"></div>
      <div class="swiper-button-prev"></div>
    </div>
  </div>
<?php else: ?>
<?php if( $services->have_posts() ): while( $services->have_posts() ): $services->the_post(); ?>
  <div class="d-sm-none d-md-block col-md-3 col-lg-3 service-col">
    <img class="rounded-circle service-icon hide" src="<?php echo the_post_thumbnail_url(); ?>" width="60">
    <a class="open-modal" href="#modal-content" data-id="<?php echo $post->ID; ?>" data-toggle="modal" style="text-decoration:none;color:black;"><h4><?php the_title(); ?></h4></a>
  </div>
<?php endwhile; ?>
<?php endif; wp_reset_postdata(); ?>
<?php endif; ?>
</div>

<div class="modal" tabindex="-1" role="dialog" id="modal-content">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title"></h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        <p class="content"></p>
      </div>
    </div>
  </div>
</div>

<script type="text/javascript">
(function($){
  $(document).ready(function(){

    $(document).on(\'click\', \'.open-modal\', function(e){
      e.preventDefault();
      var id = $(this).attr(\'data-id\');
      $.getJSON(\'wp-json/wp/v2/posts/\'+id , function(data){
        console.log(data);

      });
    });
  });
}(jQuery));
</script>
