SuluArticleBundle бросает неопределенный индекс: статья

Я пытаюсь настроить SuluArticleBundle с ElasticSearch 2.4. Я следую за документация но я продолжаю получать

[Symfony\Component\Debug\Exception\ContextErrorException] Notice: Undefined index: article

при запуске php bin/console assets:installкоманда

Это первый раз, когда я использую ElasticSearch и SuluArticleBundle, поэтому я не уверен, что это ошибка, связанная с моей настройкой ElasticSearch или настройкой комплекта.

Есть идеи, в чем может быть проблема?
