Quickbook Discount Line Items

Hello!

I've been creating a pipeline to connect Salesforce and Quickbooks.
I've gotten stuck on adding the Discount to the Quickbooks discount.

Does anyone have any experience they can offer? 
Right now I'm trying to map it over as a Discount Line Item but I keep getting this error: Line.DiscountLineDetail is missing in the request.

Not sure where I'm going wrong.

Thanks for any help!
