Examples are not working on master

Description

Failed to run first example. I just follow the steps at Developer corner section and got an Uncaught TypeError.

Not sure if I'm missing something because I haven't changed anything in the project. So it must be a bug.

Steps to Reproduce

Example:

1. git clone https://github.com/FNNDSC/ami.git
2. cd ami
3. yarn install
4. yarn example geometries_slice

Expected Results

I expected to see the example running.

Actual Results

controls.trackball.js:17 Uncaught TypeError: Class constructor rt cannot be invoked without 'new'
    at new _class (controls.trackball.js:17)
    at init (geometries_slice.js:137)
    at ./examples/geometries_slice/geometries_slice.js.window.onload (geometries_slice.js:156)
