Issue

When the child products of a configurable product are out of stock and the Display Out of Stock Products setting is enabled, GraphQL query shows the regular price of the product as 0.

Prerequisites:

Sample data is installed.

Steps to reproduce:

  1. Enable the Display Out of Stock product setting in the Commerce Admin by going to Stores > Configuration > Catalog > Inventory.

  2. Create a configurable product and assign a simple child product to it.

  3. Set the inventory of the variant (simple) product to Out of Stock.

  4. Reindex.

  5. Execute the below GraphQL query:

    code language-graphql 
    query {
  products(filter: { sku: { eq: "MH01" } }) {
    items {
      sku
      price_range {
        minimum_price {
          regular_price {
            value
            currency
          }
          final_price {
            value
            currency
          }
          discount {
            amount_off
            percent_off
          }
        }
        maximum_price {
          regular_price {
            value
            currency
          }
          final_price {
            value
            currency
          }
          discount {
            amount_off
            percent_off
          }
        }
      }
    }
  }
}

  6. Check the response section minimum_price > regular price.

Expected results:

The minimum regular price is not displayed as 0 in response.

Actual results:

The minimum regular price = 0 in response.
