Can't load Web Maps or Feature Layers

[torbenal]

Hello!

I'm working with the arcgis API for Python, but I'm having some serious issues getting it to work as expected.

I'm using portal-tier authentication.

First I try loading a Web Map directly. That gives me the following error.

from arcgis.gis import GIS

portal = GIS(url="https://maps.xyz.com/portal", username="xyz", password="xyz")
web_map_id = 'xyz'
web_map = portal.content.get(web_map_id)
portal.map(web_map)

    For further information visit https://errors.pydantic.dev/2.4/v/literal_error

Subsequently, I tried starting with an empty map, and loading Feature Layers directly

from arcgis.layers import Service

layers = Service(
    "https://xyz.com/arcgis/rest/services/xyz/xyz/FeatureServer"
)
m = portal.map()
m.basemap.basemap = 'satellite'

for lyr in layers.layers:
    m.content.add(lyr)

m.center = [xyz, xyz]
m.zoom = 30

That just outputs the basemap, with no layers to be seen.

Printing layers gives the following

<FeatureLayerCollection url:"https://xyz.com/arcgis/rest/services/xyz/xyz/FeatureServer">

Is this maybe a permission issue? I have no other ideas left. I've followed the guides in the documentation.
Also, this is all on version 2.4.0

Cheers.

Some maps have issues with our new class but we have fixed that for the next release. Are there special layer types in this map?

For the layer what type of layer are you trying to add? Rather than iterate through, try to add the entire service and see if that works.

lyr = Service("url")
map.content.add(lyr)

Another thing to check is the spatial reference of the layers vs the spatial reference of the map.
