Извещение: Попытка получить свойство non-объекта - Symfony 3

Question

Я продолжал мое изучение с symfony. Но с некоторыми ошибками, которые в этот момент. Я не могу решить. Я использую Symfony3 и Postman, я создаю UserController, и у меня есть ошибка с editAction. Когда я посылаю токен (авторизацию) и пользовательские данные (json) через метод POST. Это сообщение об ошибке, Примечание: Попытка получить свойство необъектных

500 Внутренняя ошибка сервера - ContextErrorException
