Float64 0.00 return 0 possibly removing data from lines

[Ryan-Hancock]

when trying to create a line with float64(0.00) on for example UnitAmount getting API error of "Message": "The UnitAmount field is mandatory and cannot be derived from the Quantity and LineAmount fields."

accounting.LineItem{ UnitAmount: float64(0.00), }

Edit: removing omitempty from UnitAmount and LineAmount fixes the issue.
