Get number of attachments

Hello there,

I am trying to get the number of attachments of the created post with this:

function fu_after_create_post( $post_id ) {

  // Get the ID of the outreach idea
   $current_post_id = $_POST['current_post_id'];

   // get the number of attachments created
   $attachments_number = get_posts( array( 'post_type' => 'attachment','post_mime_type' => 'image', 'post_parent' => $post_id, 'post_status'=>'published',  'numberposts' => -1 ) );
   $count = count( $attachments_number );

   //Get number of previous attachments
   $previous_photos_number = $_POST['photos_numbers'];

   //New photos number
   $total_photos_number = $count + $previous_photos_number;

   //Update the post meta photos number
   update_post_meta($current_post_id, 'wpcf-total-photos', $total_photos_number);

}

But somehow this part is not working to count the number of attachments to the created post. Any ideas why? Thx a lot!

$attachments_number = get_posts( array( 'post_type' => 'attachment','post_mime_type' => 'image', 'post_parent' => $post_id, 'post_status'=>'published',  'numberposts' => -1 ) );
   $count = count( $attachments_number );

Thx for your help and an amazing plugin!
