I have a controller method and I am creating an insert method for my entity Order which has a relationship with the User entity, one user can have multiple orders, now When I create an order and set the user to it, Doctrine tries to update the user when I don't modify it, I'm wondering what I'm doing wrong My controller method

#[Route('/new', name: 'new', methods: ['POST'])]
    public function order(
        Request $request,
        ServiceRepository $serviceRepository,
        EntityManagerInterface $manager
    ): JsonResponse
    {
        $data = json_decode(json: $request->getContent());

        //get service
        if (!property_exists($data, 'service'))
            return $this->json(['status' => false, 'message' => 'service is required']);
        $service = $serviceRepository->find($data->service);

        $order = new Order();

        $order->setUser($this->getUser());
                $order->setCreatedAt(new \DateTimeImmutable());
        $order->setTotal(0);
        $order->setStatus(Order::STATUS_OPEN);
        $order->setService($service);

        $manager->persist($order);
        $manager->flush();

        return $this->json(['status' => true]);
    }

So I try to save the order, after that I save the order item using the order id which is the order saved above, but it fails and gives me constraints error An exception occurred while executing the query: SQLSTATE[23000]: Integrity constraint violation: 1048 Column "role" cannot be empty After debugging, I found that the doctrine here wants to update my user, but I have made 0 modifications to the user, so why do I need to update it?
