Rhynamo returns null objects

Hi, I am using Rhynamo to send Rhino geometry to Revit through Dynamo. My script used to work perfectly, I had it up and running previously. However, the last time I changed something on the Rhino file and save it, the script stopped working. Rhynamo now returns null objects, and I have no idea which might be the problem. I’m attaching an image. Any thoughts on this?
