Puck.js Execution Interrupted during event processing. New interpreter error: CALLBACK,MEMORY

While running the following (example) code to read IR signals

digitalWrite(D2,0);
pinMode(D1,"input_pullup");
var d = [];
setWatch(function(e) {
   d.push(1000*(e.time-e.lastTime));
}, D1, {edge:"both",repeat:true});


var lastLen = 0;
setInterval(function() {
  if (d.length && d.length==lastLen) {
    d.shift(); // remove first element
    console.log(d.map(a=>a.toFixed(1)).toString());
    d=[];
  }
  lastLen = d.length;
},200);

I get this after a few reads:

What seems to be the issue?

How do I go about to debug this?

Thanks!
