react-dropzone - How to read files through a folder?

I am trying to use react-dropzone and I am trying to read all the images of a folder that has been dragged into the zone.

I see they have an example.

const { getDroppedOrSelectedFiles } = require('html5-file-selector')

class FolderDropzone extends React.Component {
  constructor() {
    super()
    this.state = { files: [] }
  }

  onDrop(files) {
    this.setState({
      files
    })
  }

  render() {
    return (
      <section>
        <div className="dropzone">
          <Dropzone
            getDataTransferItems={evt => getDroppedOrSelectedFiles(evt).then(files => files)}
            onDrop={this.onDrop.bind(this)}
          >
            <p>Drop a folder with files here.</p>
          </Dropzone>
        </div>
        <aside>
          <h2>Dropped files and folders</h2>
          <ul>
            {this.state.files.map(f => (
              <li key={f.name}>
                {f.fullPath} - {f.size} bytes
              </li>
            ))}
          </ul>
        </aside>
      </section>
    )
  }
}

but it does not seem to work nor does it say which 3rd party plugin is used.

My local copy gets this error

index.js:249 Failed to generate preview for file {fileObject: File(180093), fullPath: "1.jpeg", lastModified: 1538421964806, lastModifiedDate: Mon Oct 01 2018 12:26:04 GMT-0700 (Pacific Daylight Time), name: "1.jpeg", …} TypeError: Failed to execute 'createObjectURL' on 'URL': No function was found that matched the signature provided.

            } catch (err) {
              if (process.env.NODE_ENV !== 'production') {
                console.error('Failed to generate preview for file', file, err); // eslint-disable-line no-console
              }
            }
          }

I had this exact requirement which was easy as a cake as I was using antd which uses rc-upload. Works like a charm and you also get the relative path of your allowed file types.
