Failing to add SL Route Sensor with Longlat-pair

[marefr]

Using version 3.2.0b2. Is adding SL Route Sensor with Longlat-pairs supposed to work or is it not working due to deprecated API's? See screenshot/logs below.

I wanted to include my home location in the route, but maybe that's not possible using SL?

Debug logs from sl_find_trip_pos:
