1 month ago Thanks @ddunlop for your patience!
Unfortunately, I was unable to reproduce the described behavior when querying the ORS public API, see the following R script. Apparently the last location from the provided list of locations lies on a different island than the rest. There doesn't seem to be a connection mapped in OSM between these two islands, so no route can be found from/to the last and the other locations, as evident from the map below.
Could you maybe provide some details on the configuration of your ORS instance?
Cheers, Andrzej

The last location is causing all of the distance & duration results to become null. If you remove the last location from the request then the distance & duration arrays start to return numerical values.
Expected behavior
All of the locations except for the last one should return numbers. The distance & duration for the last one should be null.
