Ansible 打印调试消息结果变量

我有一个简单的任务，我无法克服。

我有一个返回 AWS EC2 实例配置的剧本。我只需要打印（显示）private_ip_address。

这是我的剧本

---
- hosts: local
  connection: local
  gather_facts: false
  become: yes
  become_method: enable

  tasks:

  - name: gather-info-ec2
    community.aws.ec2_instance_info:
      instance_ids:
        - i-XXXXXAAAAAA

    register: ec2

  - debug: msg="{{ ec2.instances.network_interfaces.private_ip_address }}"

当我像这样运行它时，我收到以下错误。

fatal: [localhost]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'list object' has no attribute 'network_interfaces'\n\nThe error appears to be in '/etc/ansible/playbooks/AWSLinuxMigration/gather_ec2_info.yaml': line 16, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n  - debug: msg=\"{{ ec2.instances.network_interfaces.private_ip_address }}\"\n    ^ here\nWe could be wrong, but this one looks like it might be an issue with\nmissing quotes. Always quote template expression brackets when they\nstart a value. For instance:\n\n    with_items:\n      - {{ foo }}\n\nShould be written as:\n\n    with_items:\n      - \"{{ foo }}\"\n"}

当我在没有 DEBUG 部分并使用-vvv的情况下执行它时，它会显示以下结果。如何提取并打印此地址？我把它缩短了一点，但你明白了
