Error when trying to save a new web map to portal arcgis 2.4.0.1 - arcgis.map.Map().save()

ATFerguson — Thu, 03 Apr 2025 16:13:03 GMT

I recently upgraded from ArcGIS Pro 3.1.1 to 3.4.3, which includes the latest Python API (2.4.0.1). I am working in a disconnected environment, so I'm unable to use conda/pip to re-install/repair python libraries in the default environment that is instlled with ArcGIS Pro. I believe I may have encountered a bug in the new arcgis.map.Map() class.

I previously used the now depricated WebMap class, and saved a new web map to ArcGIS Enterprise using the following snippet:

import arcgis gis = arcgis.gis.GIS(url=<PortalURL>, username=<PortalUsername>, password=<PortalPassword>, set_active=True) webMap = arcgis.mapping.WebMap() #add some layers webMapProperties = {'title':'Example Web Map', 'type':'Web Map', 'description':'Example description'} webMapItem = webMap.save(item_properties=webMapProperties, thumbnail=<path to thumbnail>)

Since the WebMap class has been deprecated in ArcGIS Pro 3.4 / arcgis 2.4.0, I am working on updating my script to utilize the new Map class with the following snippet:

from arcgis.map import Map gis = arcgis.gis.GIS(url=<PortalURL>, username=<PortalUsername>, password=<PortalPassword>, set_active=True) webMap = Map() webMapProperties = {'title':'Example Web Map', 'type':'Web Map', 'description':'Example description'} webMapItem = webMap.save(item_properties=webMapProperties, thumbnail=<path to thumbnail>)

The documentation for the save method suggests that Map objects have a save() method, with the following sample:

new_wm_item = wm.save(webmap_item_properties, thumbnail=’./webmap_thumbnail.png’)

When I try to call the save() method on a Map object, I am getting the following ModuleNotFoundError: No module named 'arcgis._impl._content_manager'.

When I look at my Python environment, there is a "_impl" folder in "C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\Lib\site-packages\arcgis\", but there is no "_content_manager" within the "_impl" folder.

However, "..\site-packages\arcgis\gis\_impl\_content_manager\" does exist. It looks like the API is looking in the wrong "_impl" directory to find the _content_manager class.

To make it a little more clear:
"C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\Lib\site-packages\arcgis\_impl\_content_manager" DOES NOT EXIST
"C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\Lib\site-packages\arcgis\gis\_impl\_content_manager" EXISTS

One note is that my OCD kicked in while installing the ArcGIS Pro 3.4 patches, and even though "Each patch is cumulative of all previous patch fixes", I installed 3.4.1, then 3.4.2, then the latest 3.4.3 when upgrading my ArcGIS Pro installation.

One other note is that I am running ArcGIS Enterprise 11.3. While writing up this post, I came across this page, that suggests that ArcGIS Pro 3.3 is more compatible with Enterprise 11.3. The deprecation of the WebMap class isn't present in ArcGIS Pro 3.3's default python environment (arcgis 2.3.0). I still thought this question was relevant, as it seems like a potential bug in arcgis 2.4.0.1.
