What am I doing wrong with this example of attaching javascript to my Form?

I looked at this and I seem to be doing the right things that are discussed there. I also looked through the documentation, and I found how I am supposed to add my js file to my Form.

I have run drush cr.

My form is using some AJAX, but I don’t think that should affect this as it is a separate firing js file.

I can see the attached library in the form’s render array ($form[‘#attached’][‘library’][] = ‘mymodule/my_form’;), but the javascript file doesn’t seem to do anything. I am just trying to get it to print to the console at this point.

Here is my mymodule.libraries.yml file:

mymodule.my_form:   js:     js/form_helper.js: {}   dependencies:     - core/jquery     - core/drupal     - core/drupalSettings

Here is my form_helper.js file:

(function ($, Drupal, drupalSettings) { 'use strict';     Drupal.behaviors.wStep = {     attach: function (context, settings) {       console.log('here');     }   }; })(jQuery, Drupal, drupalSettings);

Here is my hook_form_alter attaching the library:

function mymodule_form_alter(&$form, DrupalCoreFormFormStateInterface $form_state, $form_id) {   if ($form_id === 'w_form') {     $form['#attached']['library'][] = 'mymodule/my_form';   } }
