Why doesn't WordPress see customizer.js?

Question

WordPress

Conditions:
1) There are WordPress Customizer's theme settings in the /inc/customizer.php folder
2) Customizer.js is connected to it to display changes in real time

function true_customizer_live() {
  wp_enqueue_script(
    'true-theme-customizer',
    get_stylesheet_directory_uri() . '../js/customizer.js', // URL
    array( 'jquery', 'customize-preview' ),
    null,
    true
  );
}
add_action( 'customize_preview_init', 'true_customizer_live' );

3) Everything works on the local server, but not on the hosting.
Questions:
1) Why so?
2) How to fix it?
Thanks
