I recently updated a graph from Dynamo 1.3 to 2.3 and realized, that the Workbook.byfilepath in the latest version of the archi-lab package are not working.
Getting this error, when feeding a file:
I´m using Revit 2020.2, Dynamo Revit 2.3.0 and archi-lab 2020.23.7.
Also tried a few older versions of the package.
It used to work with Dynamo 1.3.4 an archi-lab 2018.13.13 on Revit 2019.
