Laravel setting up circle CI

I want to setup circle Ci, here's my full config file:

version: 2
 jobs:
     build:
         steps:
            - run: sudo apt-get install -y libsqlite3-dev
            - run: composer install -n --ignore-platform-reqs
            - run: npm install
            - run: npm run production
            - run: vendor/bin/phpunit

            - run:
               name: Start Chrome Driver
               command: ./vendor/laravel/dusk/bin/chromedriver-linux
               background: true

            - run:
               name: Run Laravel Server
               command: php artisan serve
               background: true

            - run:
               name: Run Laravel Dusk Tests
               command: php artisan dusk

however I get this error message:

build-agent version 0.0.4142-1bd195a (2017-09-11T09:57:00+0000) Configuration errors: 2 errors occurred:

• Error parsing config file: yaml: line 1: mapping values are not allowed in this context
• Cannot find a job named build to run in the jobs: section of your configuration file. This can happen if you have no workflows defined, or a typo in your 'workflows:' config.

I use AWS RDS database for my production, is it possible that during the testing it uses different database, i.e local? fake some information and then purge the database after the test? This must not affect my production database. Also the issue I have need to be fixed but I don't know what's wrong here
