Rhino Inside error message (Object reference not set to an instance of an object)

Hello, I’m having trouble with rhino inside. When I connect the model category to “element type picker” I see the attached warning. While it was working properly for walls, the issue is with the floors. Then I tried previous documents that I used the same process to generate floors, and I see that they are not working as well while they were running before. What can be the problem?

I’m having the same problem, this definition was working just fine before but now it’s all giving errors.

for the ones who has the same problem, i thouht that it was about reading the family type, then i created different family type. After i create new type i run rhino inside and it suddenlt works for both family. IDK.
