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:

Code:
import arcpy
from arcpy import env

env.workspace = r"C:PSPWeeklyWorkWeek10ArcPyAutomationAutomationDataCANADA"

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)

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_FolderCanada_Lambert_Conformal_Conic.prj")
