I've got a Jitter patch that's almost entirely instantiated in js, which basically loads & plays folders full of movies in sequence. It runs fine on my computer (2019 MBP, 8.2.2, Big Sur), but my client's ( a couple of years older, but also running Big Sur) is having a problem with it -- when he fires it up, the following notifications appear in the Console:

method setcallback called on invalid object

His movies are loading & playing (audio works) but they are not visible. I suspect there's something about the way I'm setting up my context that is somehow fragile, and I'm wondering if any js geniuses out there can take a look & tell me where I can improve.

I haven't included the whole code, just the setup and rendering. As I say, works flawlessly on my machine

//-----------------SETUP--------------------------

var incMovie = new Task(increment_movie, this);

var incFolder = new Task(read_folder, this);

var l = new JitterListener("out", callbackfun);

// store movie durations for sound flipping

    vp[i] = new JitterObject("jit.gl.videoplane", "out");

//    //post("\nplane", i, " created!");

    vm[i] = new JitterObject("jit.movie");

    ////post("\nmovie", i, " created!");

    vx[i] = new JitterMatrix(4, "char", 320, 240);

        for (var i = 0; i < movie_count; i++) {

            vm[i].matrixcalc(vx[i],vx[i]);
