Rhynamo AllGeometrytoDS Error Warning

I am getting the following message whenever I run the ‘AllGeometrytoDS’ node in Rhynamo. Any suggestions? I have tried running it with all sorts of different types of geometry…but always the same error.
Here is an example below with a very basic geometry.

Based on another post on this forum I thought it might have something to do with the version of Dynamo I am using…so I tried uninstalling and reinstalling, to no avail. This is Revit 2018 with Dynamo 2.0.1


Here is an image of the basic geometry I was testing with:

I believe this package will need to be recompiled on dynamo 2.0’s dlls. You should reach out to the author.
