No i will take care this just add ?? []

Yes exactly, we are returning an empty array, so this code:

    $options = $this->getFieldsParagraphs();
    if (!empty($options)) {
      $elements['field_reference'] = [
        '#type' => 'select',
        '#options' => $options,
        '#empty_option' => $this->t('- Select -'),
        '#title' => $this->t('Reference field'),
        '#description' => $this->t('Add button multi search on reference'),
        '#default_value' => $this->getSetting('field_reference'),
        '#states' => [
          'invisible' => [":input[name='fields[$field_name][settings_edit_form][settings][paste_clipboard]']" => ['checked' => FALSE]],
        ],
      ];
    }

Won't ever get accessed, as $options is empty. Your adjustments are definitly incorrect and will lead to a new error:

Drupal\Core\Entity\EntityStorageException: Missing bundle for entity type paragraph in Drupal\Core\Entity\ContentEntityStorageBase->doCreate() (line 125 of core/lib/Drupal/Core/Entity/ContentEntityStorageBase.php).

I just wanted to provide a quick fix for this issue. The implementation of "getFieldsParagraphs" generally feels a bit weird. We can not simply check the field definitions of the first target bundle in the "target_bundles" array, as they can differ from bundle to bundle.

@lazzyvn wouldn't it be fair to credit @grevil and me?

Thanks for the fix!!

if you want but i reject his commit
