Error while parsing the 'allow' attribute: 'midi;', 'geolocation;', 'microphone;', 'camera;', 'encrypted-media;' are invalid feature names.

I think this error comes from JSFiddle : its executes the code in an iframe which has allow attribute. You can also test almost the same code here : https://jeeliz.com/demos/faceFilter/demos/canvas2D/faceTrack...
