Issue in implementing express-paginator in nodejs

I followed https://github.com/expressjs/express-paginate#example tutorial to implement pagination in NodeJS with express-paginator

All is working well but the issue is when i click on the last page number hyperlink it keeps on redirecting me to a new incremented page number with no records displayed as there's no document in collection

For e.g if the last page number is 2 and i click on two it will keep on redirecting me to http://127.0.0.1:3000/users?page=3 again i click and again it gives http://127.0.0.1:3000/users?page=4

Can anyone please help me out?

Below is the route file : users.js

var express = require('express'),
    router = express.Router(),
    mongoose = require('mongoose'), //mongo connection
    bodyParser = require('body-parser'), //parses information from POST
    methodOverride = require('method-override'); //used to manipulate POST
    multipart = require("connect-multiparty");
    multiparty = multipart();
    fs = require('fs');
    session = require('express-session');
    paginate = require('express-paginate');


router.use(bodyParser.urlencoded({ extended: true }))
router.use(methodOverride(function(req, res){
      if (req.body && typeof req.body === 'object' && '_method' in req.body) {
        // look in urlencoded POST bodies and delete it
        var method = req.body._method
        delete req.body._method
        return method
      }
}))

var sess;

router.route('/')
    //GET all users
    .get(function(req, res, next) {
        //retrieve all users from MongoDB
        sess = req.session;
        if(sess.user){
            mongoose.model('User').paginate({}, { page: req.query.page, limit: req.query.limit }, function(err, users) {
              if (err) {
                  return console.error(err);
              } else {
                  //respond to both HTML and JSON. JSON responses require 'Accept: application/json;' in the Request Header
                  res.format({
                      //HTML response will render the users.jade file in the views/account folder. We are also setting "users" to be an accessible variable in our jade view
                    html: function(){
                        res.render('account/users', {
                              title: 'Users',
                              "users" : users.docs,
                              pageCount: users.pages,
                              itemCount: users.total,
                              pages: res.locals.paginate.getArrayPages(3, users.pages, 1),
                              has_more : res.locals.paginate.hasNextPages(users.pages)
                          });
                    },
                    //JSON response will show all blobs in JSON format
                    json: function(){
                        res.json({
                        object: 'list',
                        has_more: res.locals.paginate.hasNextPages(users.pages),
                        data: users.docs
                        });
                    }
                });
              }     
        });
        }else{
            res.redirect('/login');
        }

    })    

module.exports = router;

paginate.jade

if paginate.hasPreviousPages || paginate.hasNextPages(pageCount)
  .navigation.well-sm#pagination
    ul.pager
      if paginate.hasPreviousPages
        li.previous
          a(href=paginate.href(true)).prev
            i.fa.fa-arrow-circle-left
            |  Previous
      if pages
        each page in pages
          a.btn.btn-default(href=page.url)= page.number
      if paginate.hasNextPages(pageCount)
        li.next
          a(href=paginate.href()).next
            | Next 
            i.fa.fa-arrow-circle-right

Thanks in Advance..!!
