Uncaught TypeError: Cannot use 'in' operator to search for 'default' in undefined

[terrynguyen255]

Hi all, Thank you for this awesome lib!

Actual behavior

I've integrated it, everything works well, except an error is showing in console while loading the component:

From file: react-beautiful-dnd.js:7
Uncaught TypeError: Cannot use 'in' operator to search for 'default' in undefined
    at react-beautiful-dnd.js:7
    at react-beautiful-dnd.js:4
    at react-beautiful-dnd.js:5

on this snippet

var React__default = 'default' in React ? React['default'] : React;
var ReactDOM__default = 'default' in ReactDOM ? ReactDOM['default'] : ReactDOM;

Expected behavior

No errors

Steps to reproduce

The error doesn't occur in our sandbox

Suggested solution?
