I got warning message "WARNING 000635: Skipping feature because of NULL or EMPTY geometry" while doing Buffer_analysis {arcpy.Buffer_analysis("StreetLights",r"C:\MyExercises\Scratch\Temporary Storage.gdb\bf5","BuffDis")}. The input was point feature "StreetLights", The buffer distance was "BuffDis" (which is field of StreetLights).
Does anyone know why warning message happened?
