TypeError：“NoneType”对象在不可访问的输出中不可迭代

Question

我已经用下面的码头图像建立了一个可对接的塔台

ybalt/ansible-tower:latest

设置之后，我将容器内的应用程序升级为

apt-get upgrade

在此之后，下面是我的conatiner里面的版本

ansible 2.7.6
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/dist-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.12 (default, Jul 18 2016, 15:02:52) [GCC 4.8.4]

然后，当我执行一个使用ansible中的邮件模块的脚本时，下面的错误显示在ansible输出中

fatal: [Server]: FAILED! => {
    "changed": false, 
    "module_stderr": "Shared connection to x.x.x.x closed.\r\n", 
    "module_stdout": "\r\nTraceback (most recent call last):\r\n  File \"/home/ansible/.ansible/tmp/ansible-tmp-1549369654.27-211111564926363/AnsiballZ_mail.py\", line 113, in <module>\r\n    _ansiballz_main()\r\n  File \"/home/ansible/.ansible/tmp/ansible-tmp-1549369654.27-211111564926363/AnsiballZ_mail.py\", line 105, in _ansiballz_main\r\n    invoke_module(zipped_mod, temp_path, ANSIBALLZ_PARAMS)\r\n  File \"/home/ansible/.ansible/tmp/ansible-tmp-1549369654.27-211111564926363/AnsiballZ_mail.py\", line 48, in invoke_module\r\n    imp.load_module('__main__', mod, module, MOD_DESC)\r\n  File \"/tmp/ansible_mail_payload_bQeVQh/__main__.py\", line 381, in <module>\r\n  File \"/tmp/ansible_mail_payload_bQeVQh/__main__.py\", line 330, in main\r\nTypeError: 'NoneType' object is not iterable\r\n",

我已经开发了一个带有电子邮件配置的独立的残疾人手册，以便从任何一本剧本中参考。下面是我在剧本中定义的变量

email_host: "smtp.sendgrid.net"
email_port: 587
email_username: "username"
email_password: "password"
email_to: "admin@example.com"
email_cc:
email_subject: "test"
email_body:
email_subtype: "html"
email_secure: "try"
email_from: "noreply@example.com ( Ansible Tower )"
email_bcc:
email_attach: 

以下是我如何从其他剧本中引用上述电子邮件剧本的方法

- name: Email body on failure
  set_fact:
    email_body="Hi {{ tower_user_name }}, <br><br> Status - Failed
                                                                  <br> Issue - Build path or given build name doesn't exist
                                                                  <br> Suggested Solution - Check the validity of the build path or the build name.
                                                                  <br><br> Thank You"

- name: Sending an email
  include_role:
    name: email
    tasks_from: main.yml
  when: path_build_location.stat.exists == False

但是当该部分触发时，当第二本游戏书试图发送电子邮件时。我知道上面的错误。我的ansible配置文件中的变量将被完全注释掉，并且所有变量都会被ansible变量覆盖。所有的配置都会被重新检查，并且根据ansible文档。我甚至可以通过ansible塔发送通知，但不能通过ansible中的邮件模块发送通知。但我希望通过ansible脚本自动发送邮件。但那没有发生..。

您的实际错误在module_stdout TypeError: 'NoneType' object is not iterable中。必须引用为null或未知变量类型的变量。
