Exception has occurred: Execute Error ERROR 000622: Parameters are not valid ERROR 000628: Cannot set input into parameter Coordinate_System

Question

Not sure what I am doing wrong. Keep getting this error:

Exception has occurred: Execute Error ERROR 000622: Parameters are not valid ERROR 000628: Cannot set input into parameter Coordinate_System

Code:

import arcpy
from arcpy import env

env.workspace = r"C:\PSP\WeeklyWork\Week10\ArcPyAutomation\AutomationData\CANADA"

in_features = "lakes.shp"

properties = "PERIMETER_LENGTH_GEODESIC"

length_unit = "KILOMETERS"

coordinate_system = arcpy.SpatialReference("Projected Coordinate 
System/Continental/North America/Canada_Lambert_Conformal_Conic")

arcpy.AddGeometryAttributes_management(in_features, properties, length_unit, "", coordinate_system)

Answer 1

I think you are calling the SpatialReference incorrectly. Try doing it either as:

Just the code:

arcpy.SpatialReference(102002)

or just the name:

arcpy.SpatialReference("Canada_Lambert_Conformal_Conic")

or the filepath to a PRJ ensuring you include the extension:

arcpy.SpatialReference("C:\\My_Coords_Folder\\Canada_Lambert_Conformal_Conic.prj")
