After running many episodes of the same environment, I often get this error telling me the departLane definition is invalid:
Error: Answered with error to command 0xc4: Invalid departLane definition for vehicle 'host_0'; must be one of ("random", "free", "allowed", "best", "first", or an int>=0)
I've tried debugging it and yet I never send any value which is not permitted (mainly just add vehicles with departLane=0). Does it have to do with something else than the departLane itself?
