Валидация сериализатора Django

Я использую сериализаторы для валидации. Когда я отправляю ключ с именем ip_port, который является списком в форме-данных postman, то приходит ответ 'This field is required' для ключа ip_port. Также я прилагаю изображение postman, где я получаю ответ. Пожалуйста, помогите кому-нибудь и заранее спасибо. ответ postman при тестировании POST api

        data=request.data   
        serializer=UserRequestFormSerializer(data=data)
       
        
        if serializer.is_valid(raise_exception=True):
            # breakpoint()
            serializer.save(user=self.request.user)
            # print(serializer.data)
            sdata=serializer.data
            return Response({'detail':'User Request Form created successfully','created_data':sdata},status=status.HTTP_201_CREATED)
        return Response(serializer.errors,status=status.HTTP_400_BAD_REQUEST)
