I am not sure what version of Revit/Dynamo your using but i can’t find with in Code Block “Point.ByCoordinates” function
Try using the Dynamo Node shown below
Sorry i am using Revit 2018, Dynamo 2 with clockwork package.
I tried something simple but it still does not work.
Could you please switch on all the previews?
As @kulkul says please expand previews. Also, why did you remove the code block to extract your type?
