When adding new product programmatically to existing Cart in Magento 2, product price is 0

My goal:

Magento 2.2.5

If the customer checked to [Add Shopping Bag] option then click [Proceed to Purchase], I’ll add the [Shopping Bag] product to cart and redirect to confirm page.

Cart page 　→　Confirm page

Source Code:

public function addShoppingBag()
{
    $shoppingBagSku = $this->helper->getShoppingBagSku();
    $shoppingBagId = $this->productRepository->get($shoppingBagSku)->getId();
    $shoppingBagProduct = $this->productFactory->create()->load($shoppingBagId);
    $quote = $this->checkoutSession->getQuote();
    $params = array(
        'product' => $shoppingBagProduct->getId(),
        'qty' => 1,
        'price' => intval($shoppingBagProduct->getPrice())
    );

    $request = new MagentoFrameworkDataObject();
    $request->setData($params);
    $quote->addProduct($shoppingBagProduct, $request);
    $quote->getShippingAddress()->setCollectShippingRates(true);
    $this->quoteRepository->save($quote);
    $quote->collectTotals();
}

Problem:

I checked quote_item table, product was added but all attributes related to price are 0.
quote_address_item table is fine, all prices are correct. The problem is only with quote_item.

The things I tried

$this->cart->addProduct($shoppingBagProduct, $request);
$this->cart->save();
$this->cart->getQuote()->setTotalsCollectedFlag(false)->collectTotals()->save();

The quote_item price will be updated, but it will redirect to Cart page again because of the following code:

/magento2/source/vendor/magento/module-multishipping/Controller/Checkout.php

if ($this->_getCheckoutSession()->getCartWasUpdated(true)
    &&
    !in_array($action, ['index', 'login', 'register', 'addresses', 'success'])
) {
    $this->getResponse()->setRedirect($this->_getHelper()->getCartUrl());
    $this->_actionFlag->set('', self::FLAG_NO_DISPATCH, true);
    return parent::dispatch($request);
}

When I try to:

setCartWasUpdated(false)

It redirects to Confirm page as I want, but the quote_item price is still 0.

System > Configuration > Sales > Checkout > After Adding a Product Redirect to Shopping Cart is set to No

Question:

I searched a lot the same problem in google but no luck to archive my goal.
May be I’m missing something here, any suggestion will be appreciated.
Thank you for reading my problem.

    I need to set multishiping = false before add product.

    $quote->setIsMultiShipping(false);
$quote->addProduct($this->getShoppingBagProduct(), $quantity);

    as i promised to you, I’ll try to help you here this way ^^
    So, first of all, you should definitly refactor you’re whole method body. You’re doing a lot of stuff more than once ^^

    I can show you here an example of doing it in a magento way (untested ^^)

    <?php

class MyCustomAdd
{
    /**
     * @var MagentoQuoteApiDataCartItemInterfaceFactory
     */
    protected $cartItemInterfaceFactory;
    /**
     * @var MagentoQuoteApiCartItemRepositoryInterface
     */
    protected $cartItemRepository;
    /**
     * I assume, that this is this class!
     * @var MagentoCheckoutModelCart
     */
    protected $cart;

    public function __construct(
        MagentoQuoteApiDataCartItemInterfaceFactory $cartItemInterfaceFactory,
        MagentoQuoteApiCartItemRepositoryInterface $cartItemRepository
    ) {
        $this->cartItemInterfaceFactory = $cartItemInterfaceFactory;
        $this->cartItemRepository = $cartItemRepository;
    }

    /**
     * @throws MagentoFrameworkExceptionNoSuchEntityException The specified cart does not exist.
     * @throws MagentoFrameworkExceptionCouldNotSaveException The specified item could not be saved to the cart.
     * @throws MagentoFrameworkExceptionInputException The specified item or cart is not valid.
     */
    public function addShoppingBagToCart()
    {
        $shippingBagSku = "coole_product_sku";
        $quoteId = $this->cart->getQuote()->getId();

        $cartItem = $this->cartItemInterfaceFactory->create(['data' => [
            MagentoQuoteApiDataCartItemInterface::KEY_SKU      => $shippingBagSku,
            MagentoQuoteApiDataCartItemInterface::KEY_QTY      => 1,
            MagentoQuoteApiDataCartItemInterface::KEY_QUOTE_ID => $quoteId
        ]]);

        $this->cartItemRepository->save($cartItem);
    }
}

    You may implement my custom fix for the CartItemRepository like i did it in the Github Issue.

    Greetz,
