I'm trying to run a script that pushes the execute button on the pivot painter sop. However when I do so I receive this error "

Traceback (most recent call last):
File "labs::Sop/unreal_pivotpainter::1.1/execute", line 1, in <module>
File "labs::Sop/unreal_pivotpainter::1.1, PythonModule", line 6, in ExportAsset
File "C:/PROGRA~1/SIDEEF~1/HOUDIN~1.696/houdini/python3.7libs\hou.py", line 69118, in render
return _hou.RopNode_render(self, *args, **kwargs)
hou.OperationFailed: The attempted operation failed.
Error: FbxExporter::Initialize() failed. Error returned: File not created

Does anyone know why this is?

PS. My code looks like this:

PP2_fbx = hou.node("/obj/Geometry/PP2_Prep/PP2_MAIN/")
PP2_fbx.parm("execute").pressButton()
