Create Solids from Corridor and Corridor.GetSolids Not Working

Any feedback on this particular issue most appreciated.
I have searched the forum for an answer and although there are many posts, none that I could see that answer my issue “Object Reference not set to an instance of an object”. I have created the solids in the model in c3d using the Extract Corridor Solids tool.

I am uploading the dyn, and dwg.
Any help always appreciated.
