How to display a list of pages with a custom field on a wordpress page with a specific page ID, the value of which is equal to the ID of the current page?

Question

WordPress

Greetings!
The page structure is as follows:
Parent: Credit Cards
Pages: Card #1, Card #2, Card #3, etc.
There are pages of banks, for example, Bank #1 has page ID = 124, and some credit cards from the list have an arbitrary field, the value of which is equal to the ID of this bank, and a list of these cards should be displayed on the page of this bank.
The bank page template has the following code:

<?php 
  $nomer = get_the_ID();
  $args = array(
    'post_type'    => 'page',
    'meta_query' => array(
      array(
      'key' => 'bank_id', 
      'value' => $nomer, 
    )
    ), 
    ); 
    $pages = get_pages( $args );
      foreach( $pages as $post ){
        setup_postdata( $post );
        ?> 
          <div><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></div>
        <?php 
          }  
    wp_reset_postdata();
            
?>

the goal is to get the ID of the page of the bank where we are, and display a list of cards with an arbitrary field corresponding to the ID of a specific page.
But nothing comes out - a list of all possible pages of the site is displayed.
Tell me what I'm doing wrong, why it doesn't work?

Found a solution here :

<?php 
$nomer = get_the_ID(); // Определяем ID страницы на которой находимся
// Задаем параметры цикла:
$args = array(
  'numberposts'	=> -1,
  'post_type'		=> 'page',
  'meta_key'		=> 'bank_id',
  'meta_value'	=> $nomer
);

// С помощью WP_Query создаем переменную, содержащую все страницы со значением ЗАО в поле округ
$the_query = new WP_Query( $args );

?>

<?php if( $the_query->have_posts() ): ?>
  <?php while( $the_query->have_posts() ) : $the_query->the_post(); ?>
    <div><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></div>
  <?php endwhile; ?>
<?php endif; ?>

<?php wp_reset_query();	 // Возвращаем в норму все глобальные переменные ?>
