Stuck on an issue?

Hello

I am trying to run the basic example but i keep getting an unexpected error:

{ Error: Unexpected Error
    at IncomingMessage.<anonymous> (/Users/araza/NodeScripts/CRM-scripts/node_modules/dynamics-web-api/lib/requests/http.js:82:33)
    at emitNone (events.js:91:20)
    at IncomingMessage.emit (events.js:185:7)
    at endReadableNT (_stream_readable.js:974:12)
    at _combinedTickCallback (internal/process/next_tick.js:74:11)
    at process._tickCallback (internal/process/next_tick.js:98:9) status: 401 }

Here is my code… My client id and creds are correct because i tested by following the tutorial in this blog post:

http://alexanderdevelopment.net/post/2016/11/23/dynamics-365-and-node-js-integration-using-the-web-api/

Here is my code:

var DynamicsWebApi = require('dynamics-web-api');
var AuthenticationContext = require('adal-node').AuthenticationContext;

//the following settings should be taken from Azure for your application
//and stored in app settings file or in global variables

//OAuth Token Endpoint
var authorityUrl = 'https://login.windows.net<guid>/oauth2/token';
//CRM Organization URL
var resource = 'https://myorg.crm.dynamics.com';
//Dynamics 365 Client Id when registered in Azure
var clientId = '<my-client-id-here>';

var username = '<my-username>';
var password = '<my-password>';

var adalContext = new AuthenticationContext(authorityUrl);

//add a callback as a parameter for your function
function acquireToken(dynamicsWebApiCallback) {
  //a callback for adal-node
  function adalCallback(error, token) {
    if (!error) {
      //call DynamicsWebApi callback only when a token has been retrieved
      dynamicsWebApiCallback(token);
    } else {
      console.log('Token has not been retrieved. Error: ' + error.stack);
    }
  }

  //call a necessary function in adal-node object to get a token
  console.log('calling auth')
  adalContext.acquireTokenWithUsernamePassword(resource, username, password, clientId, adalCallback);
}


//create DynamicsWebApi object
var dynamicsWebApi = new DynamicsWebApi({
  webApiUrl: 'https://myorg.api.crm.dynamics.com/api/data/v8.2/',
  onTokenRefresh: acquireToken
});

//call any function
dynamicsWebApi.executeUnboundFunction("WhoAmI").then(function(response) {
  console.log('Hello Dynamics 365! My id is: ' + response.UserId);
}).catch(function(error) {
  console.log(error);
});

Please help. This package really looks promising and would love to use it on my project.
