如何在Ansible中使用snow_record和snow_record查找？还是我应该做些不同的事情？

Question

我正在尝试从ServiceNow收集变更记录信息。具体来说，我想查询一个主机名，并查找该服务器是否已打开变更凭单。我为Ansible遇到了这两个模块。要使它们正常运行，我收效甚微。我希望我的语法不好，或者我在做一些愚蠢的事情。这是我的剧本。

   - hosts: localhost
  connection: local
  gather_facts: no
  ignore_errors: True
  tasks:
  - name: Grab a user record
    snow_record:
      username: testuser
      password: somepass
      instance: myinstance
      state: present
      number: CHG9999
      table: change_request
      lookup_field: cmdb_ci.name=someservername

对于snow_record_find：

- hosts: mytest
  tasks:
  - name: Grab a user record
    snow_record_find:
      username: testuser
      password: somepass
      instance: someinstance
      #state: present
      #number: null??
      table: change_request
      query:
        AND:
          equals:
            active: "True"
            type: "standard"
            u_change_stage: "80"
          contains:
            u_template: "MY-Template"

关于如何使用这些模块，似乎没有很多示例或文档。我愿意使用其他方法，只要它可以通过bash，Python，Ansible或其他在Linux上运行的命令行实用程序完成即可。如果您想自己尝试，我也从https://github.com/garbled1/ansible_modules那里获取了snow_record_find模块。

snow_record的错误输出：
