Hello, I try to rename the fields of a feature class with their alias name, but I get an error message ERROR 99999. I use notebook in ArcGIS PRo 2.9.3 Any ideas why?   inFc = "A4_Moorkulisse_2022" fields = arcpy.ListFields(inFc) for f in fields: print (f.name + " - " + f.aliasName) if f.aliasName in ("OBJECTID", "SHAPE"): continue else: arcpy.management.AlterField(inFc, f.name, f.aliasName, f.aliasName)   print output: A4_Moorkulisse_2022.OBJECTID - OBJECTID A4_Moorkulisse_2022.SHAPE - SHAPE A4_Moorkulisse_2022.A3_Moorkulisse_2022_A2_Moorkulisse_2022_A1_Moorkulisse_2022_SP_R - Ref_Prozent ExecuteError: ERROR 999999: Beim Werkzeug ist ein unerwarteter Fehler aufgetreten.

Hello, I've found a script of JoshuaBixby from here: https://community.esri.com/t5/python-questions/extend-line-up-to-polygon-feature/td-p/705806/page/2 it work well to extend lines within a polygon up to the border of the polygon feature. But it couldn't work with lines which are somehow between the polygons (see attached image - in black original line). Could you think of a solution for this? I tested "Have their center in" in line 21 instead of "within" but it doesn't work ...
