Hi,
I have a service to add products to cart and we are using price module for product prices. I am adding orderlines like this
var builderConfig = new OrderLineBuilderConfig { ProductId = product.ProductID, Quantity = double.Parse(product.Quantity), UnitId = "", AddToCart = true, };
OrderLine ol = orderLineService.OrderLineBuilder(order, builderConfig);
orderLineService.Save(ol);
and getting the following error. DW version 9.5.6
<Error>
