Redirect Route abortReason caught before use

In the code

/**
 * The default aborted transition handler for new routers.
 */
function defaultAbortHandler(abortReason, location) {
  if (typeof location === 'string')
    throw new Error('Unhandled aborted transition! Reason: ' + abortReason);

  if (abortReason instanceof Cancellation) {
    return;
  } else if (abortReason instanceof Redirect) {
    location.replace(this.makePath(abortReason.to, abortReason.params, abortReason.query));
  } else {
    location.pop();
  }
}

The location is always a string, hence the rest of the code fails. I’ve got an example of the problem at https://github.com/CaseyLeask/react-router-mega-demo/commit/ffb06da63677546e3296e675aa22bb32cad21629

I’ve only just started with ReactRouter, I’m using the following which seems to work:

middleware = (req, res, next) ->
  router = Router.create
    routes: routes
    location: req.url
    onError: (error) ->
      next(error)
    onAbort: (abortReason) ->
      if abortReason.constructor.name is 'Redirect'
        {to, params, query} = abortReason
        url = router.makePath(to, params, query)
        res.redirect url
      else
        next(abortReason)

  router.run (Handler, state) ->
    # ...

What was the conclusion on this, I’m running into the same error. I need to override the onAbort function on server?
