cp to .env laravel not working in pipelines

[jaymo_h]

Hi, so it seems my pipeline file is not running the copy command to copy the .env.example file to .env 

I have tried the various copy commands, such as

- cp .env.example .env

- php -r "copy('.env.example', '.env');"

- ln -f -s .env.example .env

But none has worked, and the final builds ends up without the laravel .env file, hence the app doesn't run. I don't understand why this is the case. The pipeline runs successfully and pushes to heroku. Here is the bitbucket-pipelines.yml 

image: php:7.3

pipelines:
  default:
    - step:
        caches:
          - composer
        script:
          - cp .env.example .env
          - apt-get update
          - apt-get install -y unzip git
          - curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
          - composer install
          - php -v
          - git push https://heroku:$HEROKU_API_KEY@git.heroku.com/$HEROKU_APP_NAME.git HEAD
          - export CACHE_DRIVER=redis
          - export SESSION_DRIVER=redis
          - export DB_CONNECTION=mysql
