In case the destination is not reachable, getPath() fails and returns nil. It would be interesting to get an incomplete path passing an extra-arg. Actually, such a path can be retrieved from the closed list right after failing to reach the destination in the search expansion loop, but the expected result would probably differ depending on the search algorithm used.
