1. Data conversion failed from Surface to Curve

Hello everyone. I am working on running energy simulation for a building. when I am trying to transfer the model from Rhino to Grasshopper I get this error : 1. Data conversion failed from Surface to Curve. Does anybody know what the problem is ? How can I fix it?
Thank you in advance.
