Deployed Nodejs REST API on AWS using Elastic Beanstitch - Error cannot find custom module

I wrote my first nodejs app. It works fine on my macbook, but when I try to deploy it on AWS elastic beanstalk, I get below error.

/var/log/nodejs/nodejs.log

at Function.Module._load (module.js:310:12)

module.js:338
throw err;

Nodejs seems to be able to resolve the path for my custom userprofile module which is in the Routes directory. I tried to move userprofile.js to the root directory but it still can't resolve it.

This is the code in main.js that loads all modules

/ Download our modules

var express = require('express');    

var bodyParser = require('body-parser');    

var userprofile = require('./routes/userprofile');    

      

        
        
        
      

    

Problem: It looks like this line requires ('./routes/userprofile')

Does anyone have an idea what I might be doing wrong? Would be grateful for any help.

Thank.
