Код: Выделить всё

[Remote(action: "IsEmailAlreadyRegistered", controller: "AccountsController", ErrorMessage = "User with this email already exists /remote!")]

не вызывается. Все остальные атрибуты проверки работают, но удаленная проверка — нет. Я устанавливаю точку останова, затем отправляю данные из SwaggerUI, но все равно это не работает.
У меня пока нет внешнего интерфейса, я отправляю вызовы API из Swagger. Понятия не имею, почему.
