Cannot start Octopus


I’m trying to create a star shaped roof that is simulataneiusly a ski slope and optimised to maximise solar gain and sunlight hours using octopus, put I can’t get Octopus to start in my defnitions. Does anyone know why?

I’d be very grateful for any suggestions! The definition and rhino file are attached. If anyone has any ideas as to how to add the roof pitch as a fitness function that would be a great help as well!
