Unable to access map content property

TrishPeller — Thu, 05 Dec 2024 13:45:15 GMT

I am trying to use the api to add a layer to an existing webmap. I am trying to refactor my code based on the changes in version 2.4 (https://developers.arcgis.com/python/latest/guide/overview24/). I get an error whenever I try to access the map's content property.

wm_item = gis.content.get('0bfbcdfc20874915bc2837f9364d791f')
wm = Map(item=wm_item)
content = wm.content

I get the following error at the third line:

Can someone explain what is going on? The item id is correct.

I have the same issue. Would love feedback from the arcgis-mapping development team.
