Index was out of range

From Revit 2020 and up Dynamo for Revit is controlled by Revir updates. For Revit 2017, 2018, and 2019 the most recent version is 2.0.3.

@gokhandYZYTE Look for Dynamo Install 2.0.3 here: https://dynamobuilds.com/

Then make sure you are using the correct version of the package which those nodes are from (I think Archi-lab but I can’t confirm).
