Error with List.SortByFunction When Importing Parameters from Excel to Revit Parts Using Dynamo

encountered an error while trying to import parameters from an Excel file into Revit Parts using Dynamo. I successfully retrieved the parameter "a. Brand/Merk Objek" using Element.GetParameterValueByName, but when attempting to sort the data with List.SortByFunction, the result returns null and cannot be processed further. I have tried cleaning the data using List.Clean and ensured that the parameter exists for all elements, but the issue persists. Is there a solution to sort elements based on this parameter without errors? Thank you.

You’ll need to share a screenshot of exactly what you have and what’s happening. We can’t speak to a solution if we don’t know what the actual problem is.
