hapi服务器中出现错误

我正在构建一个简单的日志应用程序，并尝试实现模块化以使代码更可读。然而，当我启动我的应用程序时，我遇到了一些麻烦。我有两个文件，index.js是我的服务器配置，routes.js是我的路由逻辑。我编写路由的方式是根据hapi api中的api文档。

我希望有人能帮助我理解为什么我会出现以下错误：

/Users/mario/projects/loGym/node_modules/hapi/node_modules/hoek/lib/index.js:425
    throw new Error(msgs.join(' ') || 'Unknown error');
          ^

我是否没有正确导出模块？

这是我的routes.js:代码

var path = require('path');
var _ = require('underscore');
var couchbase = require('couchbase');
//Connect to database.
var db = db || new couchbase.Connection({host: 'localhost:8091', bucket: 'default'}, function(err) {
    if (err) {
      console.log('Connection Error', err);
    } else {
      console.log('Connected!');
  }
 });
console.log(db);

module.exports = [
    {method: 'GET', path: '/static/{param*}', config: { handler: { directory: { path: 'static'}}}},
    {method: 'GET', path:'/', config: landingPage},
    {method: 'GET', path:'/workouts', config: getWorkouts},
    {method: 'GET', path:'/workouts/musclegroup', config: getMusclegroup},
    {method: 'POST', path:'/addworkout', config: addWorkout}
];

var landingPage = {
    handler: function(req, reply) {
        reply.file('index.html');
    }
};
var getWorkouts = {
    handler: function (req, reply) {
        // set options for databse query
        var q ={
          descending: true,
          stale: false
        };
        // show multiple exercises - db.view(designDocument, viewName, options)
        db.view('workout', 'exercise', q).query(function(err, values){
            // use pluck method from underscore to retrieve data
            var keys = _.pluck(values, 'id');
            console.log("Keys: " + keys);
            //fetch multiple documents based on the 'keys' object
            db.getMulti(keys, null, function(err, results){
                console.log('Results: ' + results);
                var workouts = [];
                for (var prop in results) {
                  workouts.push(results[prop].value);
                }
                reply(workouts);
            });
        });
    }
};

var getMusclegroup = {
  handler: function (req, reply) {
        var q = {
          descending: true,
          stale: false
        };
        db.view('workout', 'exercise', q).query(function(err, values){
            var keys = _.pluck(values, 'id');
            db.getMulti(keys, null, function(err, results){
                var muscleGroups = [];
                for (var prop in results) {
                    console.log(typeof results);
                    console.log(results[prop].value.workout);
                    muscleGroups.push(results[prop].value.workout);
                }
                reply(muscleGroups[0]);
            });
        });
    }
};

var addWorkout = {
    handler: function(req, reply){
      var d = new Date();
      var cd = d.getDate() + "-" + (d.getMonth()+1) + "-" + d.getFullYear();
      // sets schema for workout
      var payload = {
          "personId": "personId", //to later be replaced with actual username
          "date": cd,
          "workout": [
              {
                "exercise": req.query.exercise,
                "musclegoup": req.query.musclegroup,
                "sets": [
                  {
                    "reps": req.query.reps,
                    "kg": req.query.kg
                  }
                ]
              }
          ]
      };
      // defines unique key for data
      var key = payload.personId + payload.date;
      console.log(key);
      // adds payload to database
      db.add(key, payload, function(error, results){
          if (error) {
              console.log(error);
              reply(error + "'n");
          }
          console.log(results);
          reply(payload);
      });
    }
};

这是我的index.js:代码

var Hapi = require('hapi');
var path = require('path');
var Joi = require('joi');
var rs = require('./lib/modules/routes.js');

var config= { };
var server = Hapi.createServer(process.env.PORT || 8080, config);
server.route(rs);
server.start(function(){
  console.log("Server started: " + server.info.uri);
});
module.exports = server;
