GraphQL Mapping CalculatedLineItem IDs to LineItem IDs

Hello,

I’m trying to add a discount on an order line item and can’t find a way to identify it with the LineItem ID I have when fetching the order through the REST API.

Order fetched from the REST API:

{'id': 1234,
 'email': 'email@domain.com',
 <...>
 'line_items': [{'id': 5678,
                 'variant_id': 111,
                 <...>
                 'quantity': 1,
                 'admin_graphql_api_id': 'gid://shopify/LineItem/5678'},
                {'id': 9000,
                 'variant_id': 555,
                 <...>
                 'quantity': 1,
                 'admin_graphql_api_id': 'gid://shopify/LineItem/9000'}],
 <...>
}

When calling the mutation orderEditBegin, it returns CalculatedLineItems with IDs that I can’t map to the LineItem IDs I have outside of the mutation.

Here’s the orderEditBegin mutation:

mutation beginEdit($id: ID!){
    orderEditBegin(id: $id){
        calculatedOrder {
            id
            lineItems(first:30){
                edges {
                    node {
                        id
                        quantity
                        variant {
                            sku
                            price
                            taxable
                            product {
                                productType
                                options {
                                    id
                                    name
                                    position
                                    values
                                }
                            }
                        }
                        customAttributes {
                            key
                            value
                        }
                    }
                }
            }
        }
    }
}

AFAIU the calculated order is just a temporary order between oderEditBegin and orderEditCommit. Hence, also the id’s for the line items are temporary and only available during the transaction.

After orderEditCommit you get the finished order, for sure with the correct ids.
