posts – Undefined Operate Deadly Error with Shortcode

I requested AI ChatGPT:

Are you able to develop a wordpress shortcode to create an inventory of customers of a sure position and for every one present in the event that they commented on a sure publish (counting what number of feedback they left)? The shortcode ought to write an inventory of customers and for every one say: “Sure commented (variety of feedback left)“, or “No”.

That is the reply:

perform my_custom_shortcode( $atts ) {
  $atts = shortcode_atts( array(
    'post_id' => 0, // default worth for publish ID
    'position' => '', // default worth for person position
  ), $atts );

  // get the listing of customers who've commented on the publish
  $customers = get_users_who_commented( $atts['post_id'], $atts['role'] );

  // generate the output for the shortcode
  $output="<ul>";
  foreach ( $customers as $person ) {
    $num_comments = get_number_of_comments_by_user( $atts['post_id'], $user->ID );
    if ( $num_comments > 0 ) {
      $output .= '<li>Sure, commented (' . $num_comments . ' feedback)</li>';
    } else {
      $output .= '<li>No</li>';
    }
  }
  $output .= '</ul>';

  return $output;
}
add_shortcode( 'users_who_commented', 'my_custom_shortcode' );

he It was so good to even present me use the shortcode.. all the things appeared good.

[users_who_commented post_id="123" role="author"]

.. nevertheless it would not work, “wp-die-message” seems on the web page as an alternative of the magic shortcode output. Why?

Can anybody beat the unreal intelligence?
Am I asking the flawed query in the appropriate place?
Thanks

Perhaps this can assist:
