Uncaught TypeError: Cannot read property 'start' of undefined

[cternoey]

This project looks really helpful. But when I compile and run, I get an error every time (using both chrome and Edge).

Do you know how I can fix this?

BatchSystem.prototype.setObjectRenderer = function setObjectRenderer (objectRenderer)
{
    if (this.currentRenderer === objectRenderer)
    {
        return;
    }
    this.currentRenderer.stop();
    this.currentRenderer = objectRenderer;
    this.currentRenderer.start();
};

I'm unable to reproduce this on the latest.

Got the same error after cloning the repo and doing a npm run start
