The error occurs when a product with infinite backorder cannot be ordered from the storefront.

Steps to reproduce:

  1. Set the following configuration settings:
    • Display Out of Stock Products set to Yes.
    • Backorders set to Allow Qty Below 0.
  2. Add a new custom stock and custom source.
  3. Assign a product to the custom source and make sure there is an inventory number set for it (For Example: 10).
  4. On the product edit page, open Advanced Inventory. Set the minimum quantity in the cart, (For Example: 160). The quantity must be above inventory.
  5. Go to the storefront and buy a product to create a reservation.
  6. Change the product quantity to 0. The critical point is to save the product from the Admin panel when there is a reservation.
  7. Open the product page on the storefront and try to add the product to the cart.

Expected results:

It’s possible to add the product to the cart because backorders for a quantity below 0 are allowed.

Actual results:

The product is displayed to be out of stock.
