"Fail to Convert Guid to Curve" Happened After List to Tree

As the image shows above, when I was trying to use list-to-tree helper to convert a nested list from a python component, the output is shown as Guid, and cannot be further processed in GH. I wonder how to solve this, and why this happens…

For me it works fine! Might be a Windows bug? I’m on a mac.

Works here with Rhino 7 for Windows, SR 14.

Thanks! I think maybe it’s a bug, will try again later

Thanks Dale! I’ll try to update the software and see if it could work.
