Issue

The quantity field in the products GraphQL query returns null for products that are in stock and available for sale on custom inventory stocks.

Prerequisites:

MSI is enabled.

Steps to reproduce:

  1. Create a new source.

  2. On the Admin sidebar, go to Stores > Inventory > Stock.

  3. Click Add New Stock.

  4. Expand Sales Channels and select the Websites where the stock is available.

  5. Expand Sources, click Assign Sources, select the source that you want to assign, and click Done.

  6. On the Admin sidebar, go to Catalog > Products and open an existing product in edit mode.

  7. In the Sources section, assign the custom source, set Source Item Status to In Stock, enter a non-zero value for Qty, and save the product.

  8. Confirm in Catalog > Products that the product shows a non-zero Salable Quantity for the website assigned to the custom stock.

  9. Run the following products GraphQL query for that SKU against the store view assigned to the website that uses the custom stock:

    code language-none 
    query {
  products(filter: { sku: { in: ["product_dynamic_1"] } }) {
    items {
      sku
      name
      stock_status
      quantity
      max_sale_qty
    }
  }
}

  10. Observe the response:

    code language-none 
    {
  "data": {
    "products": {
      "items": [
        {
          "sku": "product_dynamic_1",
          "name": "Simple Product 1",
          "stock_status": "IN_STOCK",
          "quantity": null,
          "max_sale_qty": 10000
        }
      ]
    }
  }
}

Expected results:

The GraphQL response returns a non-null quantity value for products that are in stock and salable on the current store/website.

Actual results:

The GraphQL response returns quantity = null while stock_status = IN_STOCK for products that are in stock and salable in the Admin when the store uses a custom MSI stock.
