How to calculate delivery in api bitrix?

Question

1C-Bitrix

There is a code that calculates the cost of delivery to a certain city.
Everything would be fine, but there is a snag.
If there is a product in the basket on the site, then everything is calculated correctly, if the basket is empty, then the delivery cost is 0, although we seem to create our own basket for the calculation
. The code is used in the product card

\Bitrix\Main\Loader::includeModule('catalog');
    \Bitrix\Main\Loader::includeModule('sale');

    $products = array(
        array(
            'PRODUCT_ID' => $bitrixProductId,
            'QUANTITY'   => 1
        ),
    );
    /** @var \Bitrix\Sale\Basket $basket */
    $basket = \Bitrix\Sale\Basket::create($siteId);
    foreach ($products as $product) {
        $item = $basket->createItem("catalog", $product["PRODUCT_ID"]);
        unset($product["PRODUCT_ID"]);
        $item->setFields($product);
    }

    /** @var \Bitrix\Sale\Order $order */
    $order = \Bitrix\Sale\Order::create($siteId, $userId);
    $order->setPersonTypeId($personTypeId);
    $order->setBasket($basket);

    /** @var \Bitrix\Sale\PropertyValueCollection $orderProperties */
    $orderProperties = $order->getPropertyCollection();
    /** @var \Bitrix\Sale\PropertyValue $orderDeliveryLocation */
    $orderDeliveryLocation = $orderProperties->getDeliveryLocation();
    $orderDeliveryLocation->setValue($userCityId);  // Город куда доставляем

    /** @var \Bitrix\Sale\ShipmentCollection $shipmentCollection */
    $shipmentCollection = $order->getShipmentCollection();

    $delivery = \Bitrix\Sale\Delivery\Services\Manager::getObjectById($deliveryId);
    /** @var \Bitrix\Sale\Shipment $shipment */
    $shipment = $shipmentCollection->createItem($delivery);

    /** @var \Bitrix\Sale\ShipmentItemCollection $shipmentItemCollection */
    $shipmentItemCollection = $shipment->getShipmentItemCollection();
    /** @var \Bitrix\Sale\BasketItem $basketItem */
    foreach ($basket as $basketItem) {
        $item = $shipmentItemCollection->createItem($basketItem);
        $item->setQuantity($basketItem->getQuantity());
    }

    /** @var \Bitrix\Sale\PaymentCollection $paymentCollection */
    $paymentCollection = $order->getPaymentCollection();
    /** @var \Bitrix\Sale\Payment $payment */
    $payment = $paymentCollection->createItem(
        \Bitrix\Sale\PaySystem\Manager::getObjectById($paySystemId)
    );
    $payment->setField("SUM", $order->getPrice());
    $payment->setField("CURRENCY", $order->getCurrency());

    $order->getDiscount()->calculate();
    $order->getDiscount()->getApplyResult();

    /** Стоимость доставки */
    $deliveryPrice = $order->getDeliveryPrice();
