Example: When creating custom config form, sometimes we need to add 'text_format ' field to our form.

Problem: When uploading an image through the CKEditor  in the Advanced HTML/Text editor, the image is not saved as "permanent". The image itself does upload at the time to sites/default/inline-images, however, coming back a day later the image has been deleted.

Solution: Add the snippet below to your custom config form to make sure your images are saved as permanent.

 * {@inheritdoc}
public function buildForm(array $form, FormStateInterface $form_state)

    $form['content'] = [
        '#type' => 'text_format',
        '#format' => 'full_html',
        '#title' => $this->t('Content'),

    return parent::buildForm($form, $form_state);

 * {@inheritdoc}
public function submitForm(array &$form, FormStateInterface $form_state)
    $content = $form_state->getValue('content')['value'];
    parent::submitForm($form, $form_state);

 * @param $content
 * @throws \Drupal\Core\Entity\EntityStorageException
private function custom_editor_record_file_usage($content)
    $uuids = _editor_parse_file_uuids($content);
    foreach ($uuids as $uuid) {
        if ($file = \Drupal::service('entity.repository')->loadEntityByUuid('file', $uuid)) {
            /** @var \Drupal\file\FileInterface $file */
            if ($file->isTemporary()) {
            \Drupal::service('file.usage')->add($file, 'editor', 'file', $file->fid->value);
