ERROR 030232: Invalid travel mode value: "The travel mode has a distance-based impedance attribute that is different from the distance attribute."

I am trying to create a service area analysis layer that uses miles (instead of kilometers) as the impedance value.

Specifically, I am trying to pass a custom TravelMode object to the arcpy.na.MakeServiceAreaAnalysis method and I'm seeing the following error:

ERROR 030232: Invalid travel mode value: "The travel mode has a distance-based impedance attribute that is different from the distance attribute."
Failed to execute (MakeServiceAreaAnalysisLayer).

Here is a minimal (although not reproducible) example of my script:

# Load dependencies import arcpy # Source Routing_ND layer network = "path/to/StreetMapPremium/NorthAmerica.gdb/Routing/Routing_ND" # Create a list of reference travel modes travel_modes = arcpy.na.GetTravelModes(network) # Create a custom travel mode around default 'Driving Distance' travel mode. new_travel_mode = arcpy.na.TravelMode(travel_modes['Driving Distance']) # Setting custom travel name and impedance value # new_travel_mode.name = 'Custom Driving Distance' new_travel_mode.impedance = 'Miles' # Create service area analysis layer result_object = arcpy.na.MakeServiceAreaAnalysisLayer( network_data_source = network, layer_name = 'test_layer', travel_mode = new_travel_mode, cutoffs = 10)

Any insight is appreciated!

slightly different answer

030232: Invalid travel mode value: <value>.—ArcGIS Pro | Documentation

'Custom Driving Distance' could be it doesn't like spaces in the name

Thank you for the reply. Unfortunately, the code fails regardless of whether I set the new_travel_mode.name attribute or not... I probably should have excluded that from my example. I just commented this out to avoid any confusion.
