I commented out "assets": "assets" from angular-cli.json, then ran the command again, that worked for me

[hpdrago]

Hey sheyooo, I'll give that a try.. Much appreciate the response.

[hpdrago]

Yeap, that worked!! thank you.

My two cents would be that in your assets you had a string instead of an array which is not following the schema.

If the problem persists, please open a new issue following our submission guidelines.

A good way to make a minimal repro is to create a new app via ng new repro-app and adding the minimum possible code to show the problem. Then you can push this repository to github and link it here.
