201-vmss-automation-dsc - Unable to evaluate template outputs: 'ipaddress'

[201-vmss-automation-dsc](https://github.com/Azure/azure-quickstart-templates/tree/master/201-vmss-automation-dsc)

Can someone tell me how to look up available properties so that I can replace failing ipaddress property?

Start with the 201-vmss-automation-dsc template and psDeploy.ps1 at line 29, then inspect the template output named ipaddress and the deployment error's listed available properties. Confirm which property should replace ipAddress and rerun the deployment; done means the template outputs evaluate successfully without DeploymentOutputEvaluationFailed.
