FOS \ OAuthServerBundle нераспознанная ошибка поля

В Symfony2 я пытаюсь реализовать FOS \ OAuthServerBundle, но получаю странную ошибку. После следования руководству Вот а также официальный путеводитель по GitHub, Я встретил ошибку, которая говорит:

Unrecognized field: randomId
500 Internal Server Error - ORMException

Это защищенная переменная в клиентском объекте / модели в FOS \ OAuthServerBundle. Я, должно быть, упускаю что-то простое здесь, но за свою жизнь я не могу понять, что.

Кто-нибудь еще сталкивался с подобной ошибкой?

Эта ошибка возникает при попытке перейти к:

http://symfony.local/app_dev.php/oauth/v2/token?grant_type=client_credentials&client_id=fd87dddb-6c29-11e4-90f3-b8ca3aa16897_fzhfyllumw0kwwgkocg80wkg8sc4ko0soww0cks4gc0ogggk&client_secret=[secret redacted]
