Pass NOVA_USERNAME & NOVA_PASSWORD gitlab CI fail

According with Nova 2.X manual

It's not advised to store your auth.json file inside your project's version control repository. However, there may be times you wish to download Nova inside a CI environment like CodeShip. For instance, you may wish to run tests for any custom tools you create. To authenticate Nova in these situations, you can use Composer to set the configuration option inside your CI system's pipeline, injecting environment variables containing your Nova username and password:

composer config http-basic.nova.laravel.com ${NOVA_USERNAME} ${NOVA_PASSWORD}

1. Create two variables in my Gitlab > Project > Settings > CI/CD with Key NOVA_USERNAME & NOVA_PASSWORD and and their respective value
2. Edit my gitlab-ci.yaml

- composer config http-basic.nova.laravel.com ${NOVA_USERNAME} ${NOVA_PASSWORD}
- composer install --prefer-dist --no-ansi --no-interaction --no-progress --no-scripts

also tried

- composer config http-basic.nova.laravel.com "$NOVA_USERNAME" "$NOVA_PASSWORD"
- composer install --prefer-dist --no-ansi --no-interaction --no-progress --no-scripts

All times get error:

    - echo "{\"http-basic\":{\"nova.laravel.com\":{\"username\":\"${NOVA_USERNAME}\",\"password\":\"${NOVA_PASSWORD}\"}}}" > ~/.composer/auth.json

I don't understand what I'm doing wrong and I don't see much about it.
