Issue

When a catalog price rule is applied to a certain customer group, items prices in the cart and order total are not calculated correctly in GraphQL.

Steps to reproduce:

  1. Create a new customer account and change its Customer Group to Wholesale.

  2. Create a new Catalog rule in Marketing > Promotions > Catalog Price Rules with the following parameters:

    • Customer Groups: WholesaleActions:
    • Apply: Apply as percentage of original
    • Discount: 50
  3. Create a new product with price=100.

  4. Log in to the frontend using the previously created customer account (if you were already logged in, log out and log in again).

  5. Add the product to the cart. The price of the product is 50 (regular price 100) and Order Total: 55 (50 + 5 of shipment cost).

  6. Execute the GraphQL API call described in customerCart query in our developer documentation.

Expected result:

Both API and frontend have the same order total with the discount introduced by the catalog rule being applied.

Actual result:

The total of the order doesn’t apply the catalog rule discount.
