AnsibleでEnterキーをシミュレートする

mysql_secure_installationコマンドを実行するためのプレイブックを作成しようとしています。

このコマンドはいくつかの質問をします。私はpexpectを使用していますが、「入力」をシミュレートする方法がわかりません。最初の質問は「ルートパスワードの入力」です。ルートパスワードを入力したくありません。 SQL Serverはローカルサーバーのみ可能です。

- name: "Secure MariaDB"
  expect:
    command: /bin/mysql_secure_installation
    responses:
      Question:
        - ''          #I want to have ansible hit enter
        - 'n'         # Type n
        - 'y'         # Type y
        - 'y'         # Type y
        - 'y'         # Type y
        - 'y'         # Type y

/bin/bash -c "echo"""、コマンド、空の行を試してみましたが、以下の応答が引き続き表示されます。
