Issue

The GraphQL query for a cart applying reward points does not consider the reward points and returns an incorrect grand total.

Steps to reproduce:

  1. Configure reward points.

  2. Create a cart and apply some reward points.

  3. Call the GetCart query from the GraphQL endpoint and retrieve your cart:

    code language-graphql
    query {
      cart(cart_id: "{CART_ID}") {
        prices {
          discounts {
            amount {
              value
            }
          }
          grand_total {
            value
          }
        }
      }
    }
    
  4. Check the grand total entry.

  5. Now check the customer’s cart total using rest API (/rest/V1/carts/mine/totals).

Expected results:

The GraphQL query for the cart returns the correct grand total which considers the reward points.

Actual results:

The GraphQL query does not consider the reward points and returns an incorrect grand total.
