The exported file by Rhynamo is empty

I’m trying to use rhynamo to export a geometry from Revit into Rhino.
The exported file can not be opened by Rhino6, ArchiCAD or Revit.
Any advice please.Thank you.

EXPORT_to_3dm.dyn (15.6 KB)
sample.rvt (1.8 MB)

I understood it. Need to use Latest version of Revit and Dynamo…
The exported file by Revit 2017.2 and Dynamo 1.3.2 is not working.
Yet by Revit 2019 and Dynamo 2.0.0, it is OK!!
