How to authenticate Cognito user pool in node js

Question

Using v1.10 of amazon-cognito-identity-js in the following nodeapp.

I have written the following: This call is made after the user registration has been confirmed and the email has been verified.

var AWS = require('aws-sdk');
var AWSCognito = require('amazon-cognito-identity-js');

router.post('/emailsignin', function(req, res, next) {
var email = req.body.email;
var pwd = req.body.password;

AWS.config.region = 'eu-west-1';
var poolData = {
  UserPoolId : AWS_USERPOOLID,
  ClientId : AWS_APPCLIENTID
};
var userPool = new AWS.CognitoIdentityServiceProvider.CognitoUserPool(poolData);
var authenticationData = {
  Username : email,
  Password : pwd,
};
var authenticationDetails = new AWS.CognitoIdentityServiceProvider.AuthenticationDetails(authenticationData);
var userData = {
  Username : email,
  Pool : userPool
};
var cognitoUser = new AWS.CognitoIdentityServiceProvider.CognitoUser(userData);

cognitoUser.authenticateUser(authenticationDetails, {
  onSuccess: function (result) {
  },
  onFailure: function(err) {
 }
});

When authenticateUser is called, I get the "ReferenceError: navigator is not defined"

It looks like a browser call is being attempted inside the node server.

I had created a github issue on this and the recommendation was to refer to "jsbn": "^0.1.0", "sjcl": "^1.0.3", "amazon-cognito-identity-js": "^1.10.0", "aws-sdk": "^2.5.3"

I made the changes to the package versions. Unfortunately it did not work with this too. I have created a sample nodejs app which tries to authenticate using email id and password.

NB : The Cognito pool is setup with email as an alias. The user has been created, confirmed and email verified.

Any pointers on how to solve the "navigator not found"?

To save some googling time there is no fix for the above error at the time of writing this but there is a workaround:
