python - Ansible Arista eos_l2_interface 模块：TypeError 不是 JSON 可序列化的

Question

版本：

• Ansible/Python 2.7
• Arista EOS 4.16.8M (7050SX)
• CentOS 7.5

我有一本遍历接口字​​典并根据需要应用更改的剧本。该剧本使用循环，虽然第一次更改总是会成功，但下一次更改将失败。

剧本：

- hosts: devswitches
  gather_facts: false
  tasks:
  - name: Configure layer 2 access interfaces
    eos_l2_interface:
      name: "{{ item.name }}"
      mode: access
      access_vlan: "{{ item.vlan }}"
    loop: "{{ interfaces }}"
    when: 
      - item.vlan is defined

变量文件：

interfaces:
  - name: Ethernet10
    description: I am et10 a trunk port 
    trunk: true
    trunknative: 399
    trunkallowed: 399
  - name: Ethernet11
    description: I am et11 an access port
    vlan: 399
  - name: Ethernet12
    description: I am et12 an access port too
    vlan: 399

事情开始了 - Ethernet10 被跳过，Ethernet11 被改变了。然后坏事发生。

TypeError 中引用的对象是本地管理员帐户的帐户密码，它包含在保险库加密变量中。传输机制是https（httpapi）：

我试过 with_items: 而不是 loop:，结果相同。这感觉像一个错误，有人有任何见解吗？
