Calling ArcPy StageService in ArcGIS Pro for a new layer returns the following error, "Selected layer does not contain a required layer type for web feature layer."

Additional Information

Workaround

1. Add a new layer.
2. Before the ArcPy CreateWebLayerSDDraft or StageService methods are called in the code, save the project in the code (or manually in ArcGIS Pro).

Below is an example:

aprx.save() 

# Replace out_sddraft path, service name and folder name 

arcpy.mp.CreateWebLayerSDDraft(map_or_layers=selected_layer,

         out_sddraft='C:/.../mydraft.sddraft',

         service_name='MyServiceName',

         folder_name='MyFolder',

         overwrite_existing_service=True,

         copy_data_to_server=True,

         enable_editing=True,

         allow_exporting=True,

         enable_sync=True)

# Replace paths

arcpy.StageService_server('C:/.../mydraft.sddraft', 'C:/.../mydraftsd.sd', 5)
