ACSD-50794: Cannot remove gift wrapping from customer order via GraphQL

Create a customer from the frontend.

Create a simple product.

Enable Gift Messages by going to Stores > Configuration > Sales > Gift Options and set Allow Gift Messages = Yes.

Create Gift Wrapping by going to Stores > Other Settings > Gift Wrapping.

Get customer token.

Create an empty cart, customerCart.

• Add products to the cart: addProductsToCart mutation
• Set billing address: setBillingAddressOnCart mutation
• Set shipping address: setShippingAddressesOnCart mutation
• Set shipping method: setShippingMethodsOnCart mutation (flatrate)
• Set payment method: setPaymentMethodOnCart mutation (checkmo)

Now check the gift wrapping Uid with this cart query:

 {
   cart(cart_id: "{{CART_ID}}") {
     available_gift_wrappings{
         uid
     }
 }
 }

Set gift wrap using setGiftOptionsOnCart.

Check the cart: cart query.

Unset gift wrap using setGiftOptionsOnCart (set value to null).

Again, check the cart: cart query.

Place order: placeOrder mutation.

Run customer query: customer.

 query {
   customer {
     firstname
     middlename
     lastname
     suffix
     email
     orders {
         items {
             order_date
             gift_wrapping {
                 design
                 uid
             }
         }
     }
     addresses {
       firstname
       middlename
       lastname
       street
       city
       region {
         region_code
         region
       }
       postcode
       country_code
       telephone
     }
   }
 }
