Strange error on crop

[dhowe]

Following the example on the README.md, in node 12.9.1 with the following package dependencies. Program is fine with Clipper.configure(canvas: canvas) and otherwise, but crashes when I add the crop command...

  "dependencies": {
    "@tensorflow/tfjs-node": "^1.5.1",
    "canvas": "^2.6.1",
    "esm": "^3.2.25",
    "face-api.js": "^0.22.0",
    "image-clipper": "^0.4.4"
  }

I'm facing the same issue, but it happens when I send the options parameter.

"dependencies": {
  "canvas": "^2.6.1",
  "cookie-parser": "~1.4.4",
  "debug": "~2.6.9",
  "express": "~4.16.1",
  "image-clipper": "^0.4.4",
  "lodash": "^4.17.15",
  "morgan": "~1.9.1"
}

This is the code that is not working:

clipper(filePath, { quality: 80 })
.crop(0, 0, 256, 512)
.toDataURL(function(dataUrl2) {
  console.log('regained the cleared data:', dataUrl2);
});

However, if instead of the "options" parameter I send a function it works:

clipper(filePath, function() {})
.crop(0, 0, 256, 512)
.toDataURL(function(dataUrl2) {
  console.log('regained the cleared data:', dataUrl2);
});

Umm, it happens when I use () => {}, try using function() {} instead and it works fine.
