I'm getting an error: ERROR in ContextFF: WebGL1 and 2 are not enabled "GL_INCOMPATIBLE". But I might want to get back to this code in the future.

FaceDetector polyfill with jeelizFaceFilter.js

class _FaceDetector {
  initPerformed = false;
  loadPerformed = false;

  constructor() {
    const canvas = document.createElement('canvas');
    this.canvas = canvas;
    this.ctx = canvas.getContext('2d');
    canvas.style.visibility = 'hidden';
    canvas.id = 'jeeFaceFilterCanvas';
    document.body.appendChild(canvas);

    console.log('canvas created', canvas);
  }

  init() {
    return new Promise((resolve, reject) => {
      global.JEELIZFACEFILTER.init({
        canvasId: 'jeeFaceFilterCanvas',
        NNCPath: '/face-detection/neuralNets/', // path to JSON neural network model (NN_DEFAULT.json by default)
        callbackReady: function(errCode, spec) {
          console.log('callbackReady', arguments);
          if (errCode){

            console.log('AN ERROR HAPPENS. ERROR CODE =', errCode);
            return reject(errCode);
          }
          // [init scene with spec...]
          console.log('INFO: JEELIZFACEFILTER IS READY');

          resolve();
        }, //end callbackReady()

        // called at each render iteration (drawing loop)
        callbackTrack: function(detectState){

          console.log('callbackTrack', detectState)

          // Render your scene here
          // [... do something with detectState]
        } //end callbackTrack()
      });

      this.initPerformed = true;
    });

  }
