rosPubMsg: attempt to index field 'vehicle' (a nil value) #25

After following the installation instructions, starting FS19, not getting in any vehicle and then immediately executing rosPubMsg true in the game console gets me this:

the line mentioned is here:

the error makes sense: I'm not in a vehicle, so g_currentMission.controlledVehicle is nil.
