[sumo-user] Reinforcement Learning in Matlab

Hello, I'm coding an RL agent in Matlab to decide the best actions at each junction for an autonomous vehicle moving into a SUMO road map. The first training simulation goes well. After the first simulation the vehicle goes outside the map and the instruction traci.vehicle.getRoadID(veh_ID) gives my an error that interrupt the entire project. To overcome this issue I introduce a Matlab try/catch. In this way, Matlab produce the final output. My problem is that SUMO says "Error: Answered with error to command 0xa4: Vehicle 'vehicle_0' is not known." and the RL training breaks.  Nevertheless Matlab doesn't present any error.
