The PATH_NOT_FOUND error message was recently changed in 98acd636d from "endpoint outside the map" to "endpoint might not be safely accessible" because this is a frequent cause of searches that cannot reach the destination. These are really two different cases, but we have to detect when an unsafe endpoint is the cause.

It will probably be difficult for users to understand an "outside the map" message since they will still see a map in their client. Maybe "outside the trip planner's coverage area" would be clearer.

This issue will be addressed when multi-objective code is stable, since the lesser number of layers in the search procedure will make analyzing search failures more straightforward.
