Once vehicle '1' leaves the simulation by arriving at it's destination, requesting it's position raises an exception. The easiest solution is to catch the exception and do nothing. You can also prevent vehicle '1' from leaving the simulation by modifying it's route or adding at <stop> on the final edge to keep it in the simulation.
