Prerequisites:

Sample data is installed.

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:

   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.
