Отсутствует ключ для перевода

Question

Когда я публикую список на сайте, над которым я работаю, возникает ошибка с переводом:

Request.CRITICAL: Uncaught PHP Exception Cocorico \ TranslationBundle \ Model \ Manager \ Exception>\ TranslationKeyIsInvalid: «отсутствующий ключ» в /var/www/Symfony/vendor/cocorico/cocorico/src/Cocorico>/TranslationBundle/Model/Manager/TranslatorManager.php строка 55

Как можно обойтиэта ошибка, чтобы позволить пользователям зарегистрировать новый список?

My TranslatorManager.php:

<?php
namespace Cocorico\TranslationBundle\Model\Manager;

use Cocorico\TranslationBundle\Model\Manager\Exception\TranslationKeyIsInvalid;
use Cocorico\TranslationBundle\Model\Manager\Exception\TranslationQuotaExceeded;
