API BaaS SDK node

Hi,

I am not able to make the API SDK for node work. And the Apigee documentation isn't helping either. :(

I have installed the node.js BaaS SDK, which is essentially the latest version of the usergrid npm package.

My questions:

1. Can Apigee BaaS support the latest usergrid npm module, or do I have to switch to an older one?

2. Here is how I am trying to initialize the usergrid connection:

const Usergrid = require('usergrid');

var config = {
  orgId: process.env.BaaS_ORG_NAME,
  appId: process.env.BaaS_APP_NAME,
  baseUrl:process.env.BaaS_URL,
  authMode:Usergrid.AUTH_CLIENT_ID,
  clientId:process.env.BaaS_CLIENT_ID,
  clientSecret:process.env.BaaS_CLIENT_SECRET
};
Usergrid.init(config);

Usergrid.GET('customer', function (error, usergridResponse, entities) {
  if (error) {
    console.error(error);
  } else {
    //my code
  }
})

I am simply getting the following error:

  UsergridResponseError {
  name: 'unauthorized',
  description: 'Subject does not have permission to access this resource',
  exception: 'org.apache.usergrid.rest.exceptions.SecurityException' }

I have double checked the config details, especially the client id/secret and the fact that these ids do have access to the org/app & resource.
