Github actions for laravel dusk failing

I use example config file of laravel dusk doc. It is failing at php artisan dusk step with this [1045] Access denied for user 'root'@'localhost' (using password: NO) (SQL: SHOW FULL TABLES WHERE table_type = 'BASE TABLE') error.

My failed github actions - https://github.com/ahp-sooyaa/koob/actions

dusk.yml file

  dusk-php:

        with:
          name: screenshots

      - name: Upload Console Logs
        if: failure()
        uses: actions/upload-artifact@v2
        with:
          name: console
          path: tests/Browser/console

The .env.example file I use with github actions.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=koob_test_db
DB_USERNAME=root
DB_PASSWORD=root

In local I use .env.dusk.local with empty database password,

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=koob_test_db
DB_USERNAME=root
DB_PASSWORD=

Does anyone know how to solve it? My first time trying with github action CI so I am struggling to make it work.
