Building Zones Surface by Surface not working?


I’m trying to create zones on a surface by surface basis. I keep getting this error. (1. Solution exception:‘NoneType’ object has no attribute ‘split’) any idea what is it about?

I also tried building the zones by mass and then decomposing the zone to have custom glazing and custom adiabatic surfaces but still gives me the same error when I try to reconstruct the zone again. GH file attached
