Pipelines as in docs gives "The 'environment' section must be a map."

My Pipelines configuration gets rejected with the following message:

The 'environment' section in your bitbucket-pipelines.yml file must be a map.

Using the docs, I created the following yml:

pipelines:
  branches:
    main:
      - step:
          image: php
          script:
            - php -v
            - apt-get update && apt-get install -y unzip
            - curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
            - composer -V
            - composer install
            - bin/console doctrine:schema:create
            - bin/console doctrine:fixtures:load
            - vendor/bin/phpunit
          services:
            - mysql
definitions:
  services:
    mysql:
      image: mysql
      environment:
        MYSQL_DATABASE: tournament
        MYSQL_RANDOM_ROOT_PASSWORD: yes
        MYSQL_USERNAME: tournament_user
        MYSQL_PASSWORD: tournament_password

What's wrong with this configuration file? Why is it rejected?

USERNAME should be USER and the values should be encapsulated in apostrophes. This works:

      environment:
        MYSQL_DATABASE: 'tournament'
        MYSQL_RANDOM_ROOT_PASSWORD: 'yes'
        MYSQL_USER: 'tournament_user'
        MYSQL_PASSWORD: 'tournament_password'
