Audio for Track Lua Trigger (not car ) It works but flags error in console

I tried to get ChatGTP to see what I was doing and its telling me to upgrade to plus. Maybe next month I will get it.
Engine.Audio.playOnce('AudioGui', 'art/sounds/Document _11.wav')
Make a folder if you do not already have one in the
BeamNG.drive\0.34\art\sounds
Paste your wav file there. And be sure to put correct name in the LUA
