Configurable product in cart is "IN_STOCK" even if the associated simple product is out of stock #3406
Description
Summary (*)
Adding configurable product with simple product that has stock and arriving to the checkout when the product has no stock available. Quiring the GRAPHQL endpoint if the product has stock result in "IN_STOCK" instead of "OUT_OF_STOCK" (only the configurable product is taken into account)
Examples (*)
When running the getCheckoutDetails graphql query on a cart with configurable product and simple product that had available qty when added to cart the query returns the product as in stock
query getCheckoutDetails($cartId: String!) {
cart(cart_id: $cartId) {
id
...CheckoutPageFragment
...ItemsReviewFragment
__typename
}
}
fragment CheckoutPageFragment on Cart {
id
items {
uid
product {
uid
stock_status
__typename
}
__typename
}
total_quantity
available_payment_methods {
code
__typename
}
__typename
}
fragment ItemsReviewFragment on Cart {
id
total_quantity
items {
uid
product {
uid
sku
name
thumbnail {
url
__typename
}
__typename
}
prices {
price {
currency
value
__typename
}
row_total {
value
__typename
}
total_item_discount {
value
__typename
}
__typename
}
quantity
... on ConfigurableCartItem {
configurable_options {
configurable_product_option_uid
option_label
configurable_product_option_value_uid
value_label
__typename
}
__typename
}
__typename
}
__typename
}
variables:
{
"cartId": "XXXXX"
}
This query is mapped to the PHP file Magento\InventoryGraphQl\Model\Resolver\StockStatusProvider where in the resolve function the product model is the configurable product only
note: the PHP file listed above looks like a copy of the PHP file Magento\CatalogInventoryGraphQl\Model\Resolver\StockStatusProvider
Proposed solution
A solution to this could be passing the cart object with the selected values of the configuration and testing each added simple product by itself
