I’ve added some paragraph in my content type. In a paragraph, I’ve added another paragraph with some data, including a media inside another content type

When I’m trying to add a media, I have this in my console :

DrupalCoreRenderElement::children() must be of the type array, null
given modules/contrib/entity_browser/entity_browser.module

Caused by the foreach part. First, I simply tried to add a condition around the foreach to see if ton only.

foreach (Element::children($form['actions']) != null

After, I had an error on the getEntity() on null . What can I do has a patch to fix it without breaking the entity_browser ? Knowing that entity_browser works fine when I edit the media

function entity_browser_form_alter(&$form, FormStateInterface &$form_state) {
  $entity_browser_dialog_edit = Drupal::service('request_stack')->getCurrentRequest()->get('_route');
  if ($entity_browser_dialog_edit == 'entity_browser.edit_form') {
    // Let's allow the save button only.
    foreach (Element::children($form['actions']) as $key) {
      $form['actions'][$key]['#access'] = $key == 'submit';
    }
    // Use Ajax.
    $form['actions']['submit']['#ajax'] = [
      'url' => Url::fromRoute('entity_browser.edit_form', ['entity_type' => $form_state->getFormObject()->getEntity()->getEntityTypeId(), 'entity' => $form_state->getFormObject()->getEntity()->id()]),
      'options' => [
        'query' => [
          'details_id' => Drupal::request()->query->get('details_id'),
        ],
      ],
      'disable-refocus' => TRUE,
    ];
  }
}

This is basicaly my structure :

| - Page
  | ---- Paragraph
    | - Slider
      | - Slide
        | - Content type
           | - Media
      | - Slide
        | - Content type
           | - Media
