React Datepicker doesn't work properly if events-polyfill is imported

Question

I have done the basic set-up for the react-datepicker package and it was working. However, in our app, we are also using events-polyfill package. And when these two packages are used at the same time, react-datepicker doesn't work properly.

import React from "react";
import ReactDOM from "react-dom";
import DatePicker from "react-datepicker";
import "events-polyfill";

import "react-datepicker/dist/react-datepicker.css";
import "./styles.css";

function App() {
  return <Example />;
}

// CSS Modules, react-datepicker-cssmodules.css
// import 'react-datepicker/dist/react-datepicker-cssmodules.css';

class Example extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      startDate: new Date()
    };
    this.handleChange = this.handleChange.bind(this);
  }

  handleChange(date) {
    this.setState({
      startDate: date
    });
  }

  render() {
    return (
      <DatePicker
        selected={this.state.startDate}
        onChange={this.handleChange}
      />
    );
  }
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);

Full error:

Uncaught TypeError: Cannot read property 'once' of null

And this is highlighted in the events-polyfill index.js file as the culprit:

options.once      = Boolean(options.once);

Totally clueless what's the issue.

Try updating events-polyfill package.

Looks like current version https://github.com/lifaon74/events-polyfill/blob/master/src/EventListenerInterceptor.js#L105 has a fix for this case.

Here is the commit with the fix https://github.com/lifaon74/events-polyfill/commit/a087bf90e2335cdad670d08499157c40ea73abdb It is aimed for 2.1.1 but npm has only 2.1.0

npm install from Git in a specific version
