Вес и стоимость доставки FedEx не устанавливаются программно при создании заказа

Я пытаюсь создать заказ программным способом, используя метод доставки FedEx. Другие методы работают нормально. Когда я устанавливаю FedEx, получаю сообщение об ошибке, например, укажите способ доставки. После отладки я узнаю, что вес и стоимость равны нулю, но я упомянул вес и стоимость продукта.

Пожалуйста, помогите мне в этом. Я попробовал фиксированную ставку, и бесплатная доставка работает, но FedEx не работает.

Зайдите в каталог, выберите товар и добавьте вес в поле атрибута веса.
