Question

hello guys when i try to loop products it's just display the div but not product info

the image of the result

or the image of the result from console

as you see it's just display the divs but not the content

this is the code:

function stsearch_products($data) {
  $args = array(
      'post_type'     => 'product', 
      'product', 'posts_per_page' => -1,
      'order'         => 'ASC' // ASC
  );
  $args['s'] = $data['search-title'];
  

  $loop = new WP_Query( $args );
  ob_start();
  if ( $loop->have_posts() ) :

      do_action( 'woocommerce_before_shop_loop' );

      woocommerce_product_loop_start(); 


          while ( $loop->have_posts() ) :

              $loop->the_post();

              wc_get_template_part( 'content', 'product' );

          endwhile;
  
      woocommerce_product_loop_end(); 


      do_action( 'woocommerce_after_shop_loop' ); 


  else :

      do_action( 'woocommerce_no_products_found' );

  endif; 

 
  wp_reset_postdata(); 
  return ob_get_clean();
