Image attachments don't get detected

This simple code snippet is detecting the first image attached to the post:

$images = get_posts(
            	array(
                	'post_type'      => 'attachment',
                	'post_mime_type' => 'image',
                	'post_parent'    => $post->ID,
                	'posts_per_page' => 1,
          		  )
      		 	 );?>
		wp_get_attachment_image($images[0]->ID );

It works on any post, except those with a page-builder structure. It seems that Page Builder hides the attached image from the function wp_get _attachment_image

Any tip?

Thanks
