Error while running "fdk validate"

I have created my first serverless app by following the steps in freshdesk document, while trying to validate using command 'fdk validate' facing the below error

Validation failed due to the following issue(s):

server/server.js::2: Parsing error: The keyword 'const' is reserved

My server.js code:

'use strict';

const unirest = require('unirest');

exports = {

  events: [

    { event: 'onTicketCreate', callback: 'onTicketCreateHandler' }


  // args is a JSON block containing the payload information.

  // args['iparam'] will contain the installation parameter values.

  onTicketCreateHandler: function(args) {

    console.log('Hello ' + args['data']['requester']['name']);



tried with below methods to rectify the error,

 - tried in different versions of node v6.10.0, v8.11.2, v10.4.0

 - tried adding the .eslintrc file to the project by eslint

 - used different IDE's VS code, Sublime, notepad

 - alternatively, use 'var' in place of 'const' even error throws in other node js syntax.

  eg: obj.then(response=>{..........}); //error throws in =>

Able to run other node projects, whereas while using fdk alone am facing this issues.

Hey Anishkumar,

Sorry for the inconvenience. We have brought in support for ES6 as part of the latest CLI.

Please make sure to install the latest CLI (sudo npm install http://dl.freshdev.io/cli/fdk-4.3.2.tgz -g).


Hai Raghuram,

Already the fdk version is up to date, am facing this issue in the latest version

Hey Anishkumar,

Looks like the new version is 4.3.3 and not 4.3.2.

Install - npm install http://dl.freshdev.io/cli/fdk-4.3.3.tgz -g

Please let us know if the issue still persists.

Hey Anishkumar,

Currently, we don't provide the ability to use scoped npm packages as part of the app and we'll be adding this in the future.

Hey Anishkumar,

We have introduced the support for scoped npm packages as part of our new CLI (version - 4.3.6). Please update to the latest version.
