Compiling in C++, Conversion from promhx Promise to Dynamic Array

[collin1021]

I am having an issue compiling in C++ using Haxe and Promhx. I am not very familiar with Haxe but the issue seems to be with functions having "double returns". The returns look something like this:
return Dispatcher.dispatchMethod(Divide, 'surfaceSplit', [_data, u, useV]) .then(function(s){ return s.map(function(x){ return new NurbsSurface(x); }); });
The error is
cannot convert from 'hx::ObjectPtr<promhx::Promise_obj.' to 'Array<Dynamic>'

This happens when trying to call buildcpp.hxml with Haxe.

From what I can understand the resulting C++ is not returning the correct type for the defined function. I so far have two instances: The resulting Intersect.cpp and NurbsSurface.cpp.

I have all the current dependencies installed. I'd appreciate any help.
