I experienced the same error, with simpler components following this design:

export class Header extends React.Component {
  render() {
  // ...

Header.propTypes = { /* ... */ }

export default Header

The solution was to export only once per file.

@cef62 thanks, so basically use require('react-docgen').resolver.findAllComponentDefinitions instead of just the resolver @nikgraf.
