Add Layer to Open ArcGIS Pro Project

kapalczynski — Mon, 25 Mar 2024 20:04:22 GMT

I am trying to simply bring in a Feature Class from a File Geodatabase into an OPEN arcPro project

Any thoughts?

Error: AttributeError: 'NoneType' object has no attribute 'addLayer'

import arcpy import fileinput import string import os from arcpy import env # FILE GDB where the feature class to bring in resides arcpy.env.workspace = r"C:\\Users\\ImportFeatureClass_Pro\\ProToolTest.gdb" # ArcPRO Project Location of the OPEN ArcPro Project aprx = arcpy.mp.ArcGISProject(r"C:\\Users\\ImportFeatureClass_Pro\\ImportFeatureClass_Pro.aprx") aprxMap = aprx.activeMap # The Feature Class from File GDB that I want brought into the OPEN ArcPro Project file_location = r"C:\\Users\\ImportFeatureClass_Pro\\ProToolTest.gdb\MasonCliiped" aprxMap.addLayer(file_location, "TOP")

Which of the three options are you using to run your code?

activemap

This property is designed to be run from within the application using a script tool, the Python window, or a Notebook. If a script is run outside of the application, a value of None will always be returned.

addLayer() isn't great since it calls for a layer file or a pre-existing.

Try addDataFromPath() instead to make a new layer from scratch.
