I have imported a pickerView widget inside the widgets folder, however when I call the widget from my index.js, it doesn't provide the widget instead it crashs my application. I have attached the image. What is wrong?

Here is the piece of code I'm using to call widget, when the button is clicked
Alloy.createWidget('danielhanold.pickerWidget', {
id: 'mySingleColumn',
outerView: $.win,
hideNavBar: false,
type: 'single-column',
selectedValues: [20],
pickerValues: [{10: 'Auburn', 20: 'Bald', 30: 'Black', 40: 'Blond', 50: 'Brown'}],
onDone: function(e) {
// Do something
},
