Solution:
The head of my "Includes" in Master_SingleServer.json was pointing to "CommerceEngine-Initialize module" instead of "IdentityServer". The task was actually looking for a folder not yet created under the web root. So, replaced with the correct/complete Master json file that has "IdentityServer" module as start point.
