3D Basemaps Solution - Error with extracting vegetation

[TrilliumLevine_EsriDE]

Hello, 

I'm working with an LAS Dataset and am attempting to extract the vegetation from it for visualization in a scene in ArcGIS Pro 2.5.2.  Vegetation is classified with codes 3, 4 and 5 in the LAS data.  The task for extracting the vegetation in the solution is generating an error, however, regarding an invalid rule package -- here's the full text of the messages generated by the script:

Any assistance would be greatly appreciated.  Thanks!

I received the same error so I went to the solution download directory (C:\Users\myname\Documents\ArcGIS\Packages\3Dbasemaps_8ee4ba\p20\rule_packages) and applied the ThematicTrees.rpk file. The symbolization worked, but no matter what units I choose, my trees are floating above ground.

Silly mistake. I had to set the trees feature class elevation to absolute height with the BASEELEV field from the tool to fix the problem. Once I converted the trees feature class to multipatch and applied the rule package (as the 3D solution task is supposed to do) the multipatch trees are correct from the beginning using absolute height and Geometry Z-values. I'm working with ESRI Tech Support on the error in the task.

Hello im getting this error in the 3d basemaps solution. do you know how to fix it?
