"ng generate application xyz" CLI not woking - angular6

Question

I am trying to add an application to existing project but it's failing when running "ng generate application xyz". Error is:
Schematic input does not validate against the Schema: {"sourceDir":"app","prefix":"app","style":"css","theme":true,"webpack":true}
Errors:
Data path "" should have required property 'name'.
I then used "ng generate application --name=xyz" and the full blown subproject was created but I get the error when I run "ng serve xyz" which says "Project 'xyz' could not be found in workspace.". I Googled but I found nothing matching my problem. All examples generate libraries but I want to generate application not library.
Do I need to manually add the newly generated sub project settings to parent angular.json file?
ng -v

According to this you need to add a --name flag in the older version of the cli.
ng generate application --name xyz
And it seems to be a fixed issue.
