Uncaught InternalError: Timeout on ADC

I am receiving this error and don't know why or how to fix this:

Uncaught InternalError: Timeout on ADC at line 6 col 30 var vOut =
E.getAnalogVRef() * E.sum(view)/(view.length*65...

Code:

var w = new Waveform(128/* your buffer size */,{doubleBuffer:true, bits:16});

w.on("buffer", function(myarr) {
  myarr.sort();
  // cut off first and last 2 elements
  var view = new Uint16Array(myarr.buffer, 2/*sizeof(uint16)*/*2, n-4);

  var vOut = E.getAnalogVRef() * E.sum(view)/(view.length*65536); // if you attached VOUT to Ao
  var vZero = 0.4;
  var tCoeff = 19.5 / 1000;
  var tempinc = (vOut - vZero) / tCoeff;
  var tempinf = tempinc * (9 / 5) + 32;

  console.log("Temp in C: " + tempinc);
  console.log("Temp in F: " + tempinf);
  //console.log(E.sum(view)/(view.length*6­5536));
});

w.startInput(A0,2000 /* Samples per second */,{repeat:true});

Console output:

Uncaught InternalError: Timeout on ADC at line 6 col 30 var vOut =
E.getAnalogVRef() * E.sum(view)/(view.length*65...
