isNextPath is not a function

Hi I'm using next-routes "^1.0.20" currently. I should note that I also tried upgrading to the newest next beta and next-routes 1.0.40, but got the same "TypeError: routes.isNextPath is not a function" error in my console.

While poking around for answers I found a few github issues where you've referenced this function. Would you mind helping me out? For some reason I can't find this function inside next-routes or next and I'm not sure what I'm getting wrong.

An Issue where you suggested it https://github.com/fridays/next-routes/issues/4#issuecomment-279955172

I thought I might be misunderstand something inside nextjs and saw another comment from you here: https://github.com/zeit/next.js/issues/1627#issuecomment-292092951

My app is getting bogged down inside an if statement. Removing reference to isNextPath "!routes.isNextPath(req.url) &&" (in my forked code and pasted below) allows the app to run but I assume I lose SSR caching as a result(?)

Here's the code:

/server/session.js

const session = require('express-session');
const FileStore = require('session-file-store')(session);
const { SESSION_SECRET } = require('./config');
const acceptLanguage = require('./acceptLanguage');
const routes = require('../universal/routes');

// TODO store more persistently (this only survives while deployment is on same machine)
const store = new FileStore({ path: '/tmp/sessions' });

module.exports = {
  configSession: session({
    secret: SESSION_SECRET,
    store,
    resave: false,
    rolling: true,
    saveUninitialized: true,
    httpOnly: true,
  }),
  defaultSessionData(req, res, next) {
    if (!routes.isNextPath(req.url) && !req.session.user) {
      req.session.user = { // eslint-disable-line no-param-reassign
        locale: acceptLanguage(req),
      };
    }
    next();
  },
};

/universal/routes.js

const nextRoutes = require('next-routes');

module.exports = nextRoutes()
  .add('/', 'index')
  .add('about')
  .add('discover')
  .add('retreat', '/retreat/:id')
  .add('track', '/track/:id')
  .add('profile', '/:slug');

Thanks
