Cannot find WebSpace error while publishing using Microsoft Azure CLI

Question

After completing one of the lessons, I received the following error when publishing a web application to my Azure account. What is WebSpace and why is Azure looking for it? I do not have this element indicated as a resource anywhere in my Azure dashboard, and I cannot find a way to create it.

E:\MyDevProjects\Visual Studio 2015\Projects\app-service-web-html-get-started>azure site create GregoryJMyWebApp --git --gitusername GregoryJ
