nodejs azure sdk Compute management error

When running the following which is identical to the documentation provided on git-hub (Minus the ToString() which causes another error) I get the following error.

CODE:

var fs = require('fs'),
    computeManagement = require('azure-mgmt-compute');

var computeManagementClient = computeManagement.createComputeManagementClient(computeManagement.createCertificateCloudCredentials({
    subscriptionId: 'sub id',
    pem: fs.readFileSync('location to pem').toString()
}));

computeManagementClient.virtualMachineImages.list(function(err, result) {
    if (err) {
        console.error(err);
    } else {
        console.info(result);
    }
});

ERROR:

                                                     ^

Ive console.log()'d the computeManagement object and this is what i get:

{ pipeline:
   { [Function: runFilteredRequest]
     add: [Function],
     get: [Function],
     post: [Function],
     delete: [Function],
     put: [Function],
     merge: [Function],
     head: [Function] },
  credentials:
   { subscriptionId: 'SUBSCRIPTION ID',
     credentials:
      { subscriptionId: 'SUBSCRIPTION ID',
        pem: 'PEM CERT INFO',
        key: undefined } },
  baseUri: 'https://management.core.windows.net',
  apiVersion: '2014-05-01',
  longRunningOperationInitialTimeout: -1,
  longRunningOperationRetryTimeout: -1,
  deployments: { client: [Circular] },
  extensionImages: { client: [Circular] },
  hostedServices: { client: [Circular] },
  loadBalancers: { client: [Circular] },
  operatingSystems: { client: [Circular] },
  serviceCertificates: { client: [Circular] },
  virtualMachineDisks: { client: [Circular] },
  virtualMachineExtensions: { client: [Circular] },
  virtualMachines: { client: [Circular] },
  virtualMachineOSImages: { client: [Circular] },
  virtualMachineVMImages: { client: [Circular] } }

That doesn't have a virtualMachineImages method which makes sense. Even more interesting is every property is a duplicate of the original computeManagement object, with every property off that a duplicate and so on.

What on earth is going on here? Could anyone enlighten me as to what im doing wrong? The documentation is pitiful on the Compute Management module and even when copied directly doesn't work. I've Googled to my wits end so posting here is a last resort. Everything on Google is regarding running Node on Azure however I want to manage Azure Virtual Machines through Node.JS.

Thanks all
