Trying to call cognito token from postman script

Working within Postman I'm trying to call a jwtToken from Cognito using node's aws-sdk but I'm getting the following error:

There was an error in evaluating the Pre-request Script: Error: Cannot find module 'aws-sdk'

This is my scrypt:

const AWS = require('aws-sdk');
var authenticationData = {
    Username: 'username',
    Password: 'password',
};
var authenticationDetails = new 
AmazonCognitoIdentity.AuthenticationDetails(authenticationData);
var poolData = {
    UserPoolId: 'us-east-1_xxxxxx',
    ClientId: 'xxxxx'
};
var userPool = new AmazonCognitoIdentity.CognitoUserPool(poolData);
var userData = {
    Username: 'username',
    Pool: userPool
};
var cognitoUser = new AmazonCognitoIdentity.CognitoUser(userData);
cognitoUser.authenticateUser(authenticationDetails, {
    onSuccess: function(result) {
        var accessToken = result.getAccessToken().getJwtToken();
        var idToken = result.idToken.jwtToken;
    },
});
pm.globals.set("token", idToken);

So far the only commands I ran where: brew install node
 and npm install aws-sdk

I'm sure I'm missing some sort of configuration to call the module, Any help will do! Thnx!

Seems like Postman Sandbox cannot obtain a script's external dependencies.

You can leverage eval() Javascript function to import additional Javascript code by having the code stored within a postman global or environment variable.

Example: eval(postman.getGlobalVariable('aws-sdk-code'))

See TIP #5: http://blog.getpostman.com/2017/07/28/api-testing-tips-from-a-postman-professional/

Also, you might encounter a later issue once the code executes as it seems you are requesting for AmazonCognitoIdentity class in the amazon-cognito-identity-js package.
