Cannot set property 'settings' of undefined

I use jquery-lazyload 1.9.7 with reactjs, it works well. I try to use lazyload 2.0.0-beta.2 with reactjs, I got errors like

Uncaught (in promise) TypeError: Cannot set property 'settings' of undefined
    at LazyLoad (lazyload.js:78)

my react component call lazyload like

  componentDidMount() {
    const images = this.node.querySelectorAll('.lazyload')
    lazyload(images, {
      threshold: 200,
    })
  }

I think it should be a bug.

Do not use lazyload() instead of new lazyload()

I had the same problem and it was because I was not calling properly Lazyload. Initially I was doing this:

var lazyload = require('lazyload.js');
lazyload();

But, what I should do is:

var lazyload = require('lazyload.js');
var obj = new lazyload();
