Symfony POST 请求正在通过验证，但它应该给出错误-PHP中文网问答

订单模型.php

订单类型.php
add('id', IntegerType::class)
            ->add('customerId', IntegerType::class)
            ->add('items', CollectionType::class, [
                'entry_type' => ItemType::class
            ])
            ->add('total', TextType::class);
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'data_class' => OrderModel::class
        ]);
    }
}
OrderController.php：
#[Route('/order', name:'order_new', methods: 'POST')]
public function create(ManagerRegistry $doctrine, Request $request): JsonResponse|Response
{
    $form = $this->createForm(\OrderType::class);
    if ($request->isMethod('POST')) {
        $form->submit($request->request->get($form->getName()));
        if(!$form->isSubmitted() || !$form->isValid()){
            return $this->handleView($this->view($form, Response::HTTP_BAD_REQUEST));
        }
    }
}
我的帖子请求：
{
  "id": "dsdas",
  "customerId": 1,
  "items": [
      {
          "productId": 1,
          "quantity": 1,
          "unitPrice": "250.25",
          "total": "250.25"
      },
      {
          "productId": 1,
          "quantity": 1,
          "unitPrice": "250.25",
          "total": "250.25"
      }
  ],
  "total": "500.50"
}
此请求正在通过验证，我正在尝试弄清楚。任何想法将不胜感激。
