JPA OneToMany не удается создать сущность. Ошибка ConstraintViolationException

@Test
    public void add() {
        Client client = clientRepo.findById(6L).get();
        BankCard bankCard = new BankCard();
        bankCard.setName("tinkov");
        bankCard.setNumber("321312321312");
        client.setCards(Sets.newSet(bankCard));
        client.setUsername("GERa");
        clientRepo.save(client);
    }

При выполнение кода получаю ошибку, но причина мне не ясна. Почему при создание банковской карты не находится user_id ведь я создаю через него, почему orm не исправляет этой проблемы ? Как исправить проблему ?
