Document.NewFootPrintRoof parameter problem

I’m trying to create a roof on python, there is this function on Revit API for it:

public FootPrintRoof NewFootPrintRoof(
CurveArray footPrint,
Level level,
RoofType roofType,
out ModelCurveArray footPrintToModelCurvesMapping
)

use it on my python script: footprintRoof = doc.Create.NewFootPrintRoof(footprint, levelId, roof, footPrintToModelCurveMapping)
But i get this error:

TypeError: expected StrongBox[ModelCurveArray], got ModelCurveArray

The problem is that i need to pass a reference parameter ( Using prefix out on C# for example ) but i cant find a way to pass it on python, there is a solution for this?
