BlendLuxCore Latest: argument types of Scene.DefineBlenderMesh does not match C++ signature (blender3.6)

[TobiasP92]

I wanted to test BlendLuxCore with the latest version of blender and got the following Error:

ERROR: Python argument types in

Scene.DefineBlenderMesh(Scene, str, int, int, int, int, int, int, int, bool, list, list, int, int, NoneType, tuple, list, NoneType)

did not match C++ signature:

DefineBlenderMesh(luxcore::detail::SceneImpl*, std::__cxx11::basic_string<char, std::char_traits, std::allocator >, unsigned long, unsigned long, unsigned long, unsigned long, unsigned long, unsigned long, boost::python::api::object, boost::python::api::object, unsigned long, unsigned int, boost::python::tuple, boost::python::api::object, boost::python::api::object)

The error appears both on windows and linux with the latest blender version (3.6) and the latest BlendLuxCore build (2.7 beta).
