Deploy to heroku is not working using yo angular-fullstack:heroku #1966

Hello, I have just created my app, working perfectly in localhost but when I try to deploy to Heroku I have problems.

First of all, using yo angular-fullstack:heroku I get this error:
(!) NamedBase constructor is deprecated. See https://github.com/yeoman/generator /issues/882 ? Name to deploy as (Leave blank for a random name):

How can deploy into Heroku? must I wait when that issue it will be fixed?

I have tried to deploy manually, following the steps: https://github.com/angular-fullstack/generator-angular-fullstack/issues/1920 https://github.com/angular-fullstack/generator-angular-fullstack/issues/1950 but I can't get sorted.

After installing angular-fullstack, have I to create a heroku app?

1. cd dist
2. heroku create
3. git init
4. git add .
5. git commit -m "first commit"
6. git push heroku master
7. heroku open

Could you explain me the steps to create an app and deploy to heroku instead of using yo angular-fullstack:heroku ??

Thanks in advance
