      Mastodon now requires that these variables are set:

        - ACTIVE_RECORD_ENCRYPTION_DETERMINISTIC_KEY
        - ACTIVE_RECORD_ENCRYPTION_KEY_DERIVATION_SALT
        - ACTIVE_RECORD_ENCRYPTION_PRIMARY_KEY

      Run `bin/rails db:encryption:init` to generate new secrets and then assign the environment variables.
      Do not change the secrets once they are set, as doing so may cause data loss and other issues that will be difficult or impossible to recover from.

  end

  next unless Rails.env.production? && value.end_with?('DO_NOT_USE_IN_PRODUCTION')

  abort <<~MESSAGE

    It looks like you are trying to run Mastodon in production with a #{key} value from the test environment.

    Please generate fresh secrets using `bin/rails db:encryption:init` and use them instead.
