Hello.
For some reason I keep getting the warning: "FilterRule.CreateRule operation failed. Method not found: ‘Int64 Revit.Elements.Category.get_Id()’.
I’m attempting to create a dynamo script that creates a filter and overrides the line color to my desired input. The line colors of all duct systems will be modified.
Attached you’ll find my Dynamo script as well as the python script I borrowed from [Categories vs. Category.ByName Discrepancy in 2.13 - #2 by solamour](https://Categories vs. Category.ByName Discrepancy in 2.13)

filter = ElementMulticategoryFilter(typed_list)
output = FilteredElementCollector(doc).WherePasses(filter).ToElements()

# if error occurs anywhere in the process catch it

if None == errorReport:
OUT = output

OUT = errorReport
