ExpressJS req.params is empty on nested routers

I use a routing setup that uses my api folder directory structure to intuitively configure routes. However, in cases where I use the folder name to represent the route parameter, req.params is undefined in the controller.

The route with the problem:

GET /api/google/accounts/:account_id/analytics/profiles/

Here is my route loader. It basically does glob in the api folder, looking for files with a name routes.jsand does app.useon the appropriate route (determined from the folder structure).

  // load routers
  files = glob.sync("api/**/routes.js");

  console.log(files);
  // [ 'api/campaigns/routes.js',
  //   'api/google/accounts/:account_id/analytics/profiles/routes.js',
  //   'api/google/accounts/routes.js',
  //   'api/google/urls/routes.js',
  //   'api/users/routes.js' ]

  // use each router on the appropriate route
  for(var i=0;i<files.length;i++) {

    route  = "/" + files[i].split("/routes.js")[0];

    console.log(route);
    // '/api/google/accounts/:account_id/analytics/profiles'

    router = require(path.join(__dirname, files[i]))(config);
    routes = router.stack;
    app.use(route, router);

    // list all registered routes for this router
    for(var j=0;j<routes.length;j++) {
      routeDebug(("      " + Object.keys(routes[j].route.methods)[0].toUpperCase()).slice(-6) + " " + route + routes[j].route.path);
    }
  }

Folder structure "api":

./api
./api/campaigns
./api/campaigns/controller.js
./api/campaigns/model.js
./api/campaigns/routes.js
./api/users
./api/users/controller.js
./api/users/model.js
./api/users/routes.js
./api/google
./api/google/accounts
./api/google/accounts/:account_id
./api/google/accounts/:account_id/analytics
./api/google/accounts/:account_id/analytics/profiles
./api/google/accounts/:account_id/analytics/profiles/controller.js
./api/google/accounts/:account_id/analytics/profiles/routes.js
./api/google/accounts/controller.js
./api/google/accounts/model.js
./api/google/accounts/routes.js
./api/google/urls
./api/google/urls/controller.js
./api/google/urls/routes.js

In the above loop, routeDebug is a wrapper around the debug npm package. Output:

  routes    GET /api/campaigns/ +0ms
  routes   POST /api/campaigns/ +2ms
  routes    GET /api/campaigns/:campaign_id +1ms
  routes    PUT /api/campaigns/:campaign_id +0ms
  routes DELETE /api/campaigns/:campaign_id +0ms
  routes    GET /api/google/accounts/:account_id/analytics/profiles/ +128ms
  routes    GET /api/google/accounts/ +4ms
  routes   POST /api/google/accounts/ +0ms
  routes   POST /api/google/urls/ +3ms
  routes    GET /api/users/ +12ms
  routes   POST /api/users/ +0ms
  routes    GET /api/users/:user_id +0ms
  routes    PUT /api/users/:user_id +0ms
  routes DELETE /api/users/:user_id +0ms

Thus, we see that this route is configured as expected. But req.params is undefined. Other routes do not have this problem.

req.params ? , ?

Express.js

var router = require("express").Router({mergeParams: true});
