Console error while using Popover component on a React 16 application

[nandukalidindi]

The error is two phased.

• propTypes error on the react-overlays component because older version of it is used

• After upgrading the react-overlays component to it's latest then in the application this error is thrown in the console. Also instead of showing a popover the application is navigated to a blank page.

invariant.js:42 Uncaught Error: _processChildContext is not available in React 16+. This likely means you have multiple copies of React and are attempting to nest a React 15 tree inside a React 16 tree using unstable_renderSubtreeIntoContainer, which isn't supported. Try to make sure you have only one copy of React (and ideally, switch to ReactDOM.createPortal).
