add_action() not working for admin

Question

Making my own custom plugin and using add_action several times without a problem with one exception. Currently function below are located in functions.php in the appropriate themes folder.

function enqueue_custom_scripts() {
   error_log('enqueue_custom_scripts function is executing'); // In enqueue_custom_scripts
   
   wp_enqueue_script('custom-ajax-script', get_stylesheet_directory_uri() . '/js/custom-ajax-script.js', array('jquery'), null, true);

   wp_localize_script('custom-ajax-script', 'ajax_object', array(
       'ajax_url' => admin_url('admin-ajax.php'),
       'nonce'    => wp_create_nonce('my-custom-ajax-nonce'),
   ));
}
add_action('wp_enqueue_scripts', 'enqueue_custom_scripts');

I have tried several version of this, in several files including plugin main file. Note: Not even the error_log trigger. The odd thing is that it works if user not logged in. Probably some stupid mistake I made so help is appreciated.

Answer 1

As noted in the documentation, the wp_enqueue_scripts hook (emphasis mine):

...is the proper hook to use when enqueuing scripts and styles that are meant to appear on the front end.

If you want to enqueue scripts in the admin, you need to use admin_enqueue_scripts.
