Error in console after build using babel presets latest

[sabarnix]

There seems to be an error importing HTML5Backend Here's my babel config in package.json

"babel": {
    "presets": [
      [
        "latest",
        {
          "es2015": {
            "modules": false
          }
        }
      ],
      "react",
      "stage-0"
    ],
    "env": {
      "production": {
        "only": [
          "app"
        ],
        "plugins": [
          "transform-react-remove-prop-types",
          "transform-react-constant-elements",
          "transform-react-inline-elements"
        ]
      },
      "test": {
        "plugins": [
          "istanbul"
        ]
      }
    }
  }

And here's the webpack.config.js file

  {  
  entry:  [
    path.join(process.cwd(), 'app/app.js'),
  ],
  output: {
    path: path.resolve(process.cwd(), 'build'),

    new webpack.DefinePlugin({

I've imported Html5Backend as shown in the docs

import HTML5Backend from 'react-dnd-html5-backend';

Although the webpack build completes successfully, on running, the following error is shown in the browser console.
