AWS-RunAnsiblePlaybook模板时发生未处理的异常

Question

我正在尝试运行AWS-RunAnsiblePlaybook，同时查找参数存储区以获取mysql的凭证。似乎与aws_ssm查找模块有关。

我收到以下错误。

这是我的剧本

- hosts: all
  become: yes
  vars:
    mysql_hostname: "{{ lookup('aws_ssm', 'mysql_hostname', region='ap-southeast-2') }}"
    mysql_database_name: "{{ lookup('aws_ssm', 'mysql_database_name', region='ap-southeast-2') }}"
    mysql_user_name: "{{ lookup('aws_ssm', 'mysql_user_name', region='ap-southeast-2') }}"
    mysql_password: "{{ lookup('aws_ssm', 'mysql_password', region='ap-southeast-2') }}"

  tasks:
    - name: gather ec2 facts
      action: ec2_metadata_facts

    - name: install bzip2 on redhat or centos instances
      yum: name=bzip2 state=present
      when: ansible_os_family == "RedHat"

    - name: install bzip2 on debian or ubuntu instances
      apt: name=bzip2 state=present
      when: ansible_os_family == "Debian"

    - name: dump database
      mysql_db: name={{mysql_database_name}} login_host={{mysql_hostname}} login_user={{mysql_user_name}} login_password={{mysql_password}} state=dump target=/tmp/{{mysql_database_name}}.sql.gz'''
