The error is
Warning: Element.SetParameterByName operation failed.
The best overloaded method match for ‘Revit.Elements.InternalUtilities.ElementUtils.SetParameterValue(Autodesk.Revit.DB.Parameter, double)’ has some invalid arguments
It used to work before. But it doesn’t work since I use Revit 2020.
My Dynamo version is:
Dynamo core 2.1.0.7500
Dynamo Revit 2.1.0.7733
Archi-lab version 2019.2.25
