How to turn the camera light (torch) off?

Question

I'm creating an app to read barcodes. I'm using QuaggaJS as a barcode reader library. My problem is that I can turn the torch on, but I can't turn it off.

var track = Quagga.CameraAccess.getActiveTrack();
track.applyConstraints({advanced: [{torch:true}]}); //Torch is on
track.applyConstraints({advanced: [{torch:false}]}); //Torch still on :(

Is there a way to turn the torch off?
