ReflectionException с Symfony и Sonata, «Класс не существует»

Я испытываю проблему, пытаясь вписать свои сущности в комплект администратора Sonata. У меня есть что-то вроде 5 сущностей, которые точно перечислены и просматриваются в комплекте, но я не могу редактировать или создавать новую запись.

Когда я пытаюсь редактировать или создавать, я получаю ReflectionException ошибка:

Класс не существует

Я попытался решить эту проблему, чтобы работать с пространствами имен (перемещая контроллер в том же пространстве имен, что и файлы администратора, или около того) или настроить контроллер администратора, чтобы рассказать ему о моих сущностях («-> add (‘Individual’, ‘entity’, array (‘class’ => ‘Platform \ ProjectBundle \ Entity \ Individual’)) «вместо -> add (‘индивидуальный’)).

Моя сущность называется Biosample. Вот файл Entity:
