Исключение сопоставления в Symfony / Doctrine: целевой объект App \ DocumentBundle \ File не найден в «App \ DocumentBundle \ Entity \ Document # file»

Question

Я пытаюсь обновить приложение, работающее на Symfony 3.4, до версии 4.4. Я уже сделал несколько изменений и адаптаций в соответствии с официальной документацией для обновления Symfony. Тем не менее, я застрял сейчас со следующей ошибкой, которая появляется, когда я пытаюсь запустить команду в терминале или получить доступ к приложению через браузер.

Исключение отображения

Doctrine\ORM\Mapping\MappingException:
The target-entity App\DocumentBundle\File cannot be found in 'App\DocumentBundle\Entity\Document#file'.

Сам код должен хранить документ и предлагать возможность прикреплять файлы к документам. Поэтому я использовал Vich / Uploader-Bundle и подозреваю, что ошибка как-то связана с Vich.
