Honeybee daylight simulation error curved roof

Hi!

Can someone help me with this error I get from honeybee daylight simulation?

I try to do a simple simulation with a skyroof in a curved roof. Is this even possible or should i divide my "roof" surface into planar surfaces? Someone has an idea how to do this? The error I get is: Solution exception:index out of range: 1

thanks alot!
