AWS Lambda Node.js 6.10 : "errorMessage": "Cannot find module 'cfn-response'", - node.js

Question

I am trying to deploy a lambda function in Nodejs 6.10 and I am getting this error:
Response:
{
"errorMessage": "Cannot find module 'cfn-response'",
"errorType": "Error",
"stackTrace": [
"Module.require (module.js:497:17)",
"require (internal/module.js:20:19)",
"Object. (/var/task/index.js:2:20)",

}

I am using Node.js 6.10 version for this method and did inline code edit.
Code I am trying to execute:
var response = require('cfn-response');
exports.handler = function(event, context) {
var input = parseInt(event.ResourceProperties.Input);
var responseData = {Value: input * 5};
response.send(event, context, response.SUCCESS, responseData);
};
Any clues?

Mostly it is because of the way zipping the files making the problem. Instead of zipping the root folder you have to select all files and zip it like below,
Please upload all files and subfolders like below. Please include node_modules folder as well in the zip.
