Dialog api v2 - Unexpected error while acquiring application default credentials: Could not load the default credentials

i am trying to implement a chat bot application with google dialog flow. i was fallowing this github tutorial https://github.com/dialogflow/dialogflow-nodejs-client-v2 to implement api. this is my code

var express = require('express');
var router = express.Router();
const projectId = 'my-project-id'; //https://dialogflow.com/docs/agents#settings
const sessionId = 'random no';
const query = 'hello';
const languageCode = 'en-US';
// Instantiate a DialogFlow client.
const dialogflow = require('dialogflow');
const sessionClient = new dialogflow.SessionsClient();

// // Define session path
// const sessionPath = sessionClient.sessionPath(projectId, sessionId);
/* GET home page. */
router.get('/', function(req, res, next) {


});

module.exports = router;

once i start my application i am getting the bellow error

(node:6436) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 3): Error: Unexpected error while acquiring application default credentials: Could not load the default credentials. Browse to https://developers.google.com/accounts/docs/application-default-credentials for more information.

Browse to https://developers.google.com/accounts/docs/application-default-credentials for more information.

so i tried to figure out the issue and found that i need to Set up authentication with a service account. and i did that downloaded the key file that contain required keys and ran the command 

set GOOGLE_APPLICATION_CREDENTIALS=[PATH]

but doing this also did nothing. is there a way to manually provide this key file from the code instead of setting an environment variable.

According to this link and github repo here you should be able to set the credentials in const sessionClient:

const sessionClient = new dialogflow.SessionsClient({ keyFilename: "relative/path/to/key.json" })
