login to [sap] cloud foundry and get api response using nodejs wrapper - node.js

Question

I have a scenario, where I am trying to fetch the API responses of the following host url of my account spaces and orgs in cloudfoundry SAP.
https://api.cf.eu10.hana.ondemand.com
I am using nodejs (wrapper cf-client) script to authenticate but whenever I try to login it provides below error
Error: {"error":"unauthorized","error_description":"{"error":"invalid_grant","error_description":"User authentication failed: INVALID_AUTHORIZATION_HEADER_LENGTH"}"}
Here is my nodejs script
"use-strict";
const endpoint = "https://api.cf.eu10.hana.ondemand.com";
const username = "myusername"; //I have created a trial account
const password = "Password"; //I have created a trial account
const JsonFind = require('json-find');
const fs = require('fs')
const util = require('util');
const dJSON = require('dirty-json');
const CloudController = new (require("cf-client")).CloudController(endpoint);
const UsersUAA = new (require("cf-client")).UsersUAA;
const Apps = new (require("cf-client")).Apps(endpoint);
const Spaces = new (require("cf-client")).Spaces(endpoint);
const Orgs = new (require("cf-client")).Organizations(endpoint);
CloudController.getInfo().then( (result) => {
UsersUAA.setEndPoint(result.authorization_endpoint);
return UsersUAA.login(username, password);
}).then( (result) => {
Orgs.setToken(result);
return Orgs.getOrganizations();
}).then((result) => {
all_orgs = result.resources //returns api
get_orgs=util.inspect(all_orgs, {depth: null});
console.log(get_orgs)
});
What I have seen is when I normaly login with cf client it requires sso passcode along with username password.
how can i provide that here or any idea how can I login here and fetch the data.

Since I did little more research on this and found out that a token generator can be used to overcome this, below code.
"use-strict";
var totp = require('totp-generator');
const endpoint = "https://api.cf.eu10.hana.ondemand.com";
var token = totp('clientsecretidgoeshere');
const username = "myusername"; //I have created a trial account
const password = "Password"+token; //I have created a trial account
const JsonFind = require('json-find');
const fs = require('fs')
const util = require('util');
const dJSON = require('dirty-json');
const CloudController = new (require("cf-client")).CloudController(endpoint);
const UsersUAA = new (require("cf-client")).UsersUAA;
const Apps = new (require("cf-client")).Apps(endpoint);
const Spaces = new (require("cf-client")).Spaces(endpoint);
const Orgs = new (require("cf-client")).Organizations(endpoint);
CloudController.getInfo().then( (result) => {
UsersUAA.setEndPoint(result.authorization_endpoint);
return UsersUAA.login(username, password);
}).then( (result) => {
Orgs.setToken(result);
return Orgs.getOrganizations();
}).then((result) => {
all_orgs = result.resources //returns api
get_orgs=util.inspect(all_orgs, {depth: null});
console.log(get_orgs)
});
