使用Ansible执行net_put时遇异常错误，寻求技术支持

已成功通过SSH连接到目标交换机，但使用Ansible net_put 模块通过SCP传输文件时出现异常。直接在同一控制服务器上发起SCP会话可正常传输目标文本文件，但Ansible执行剧本时无法完成传输。

已开启Ansible详细日志，报错信息如下：

During handling of the above exception, another exception occurred:

    Traceback (most recent call last):

    }

谷歌搜索未找到有效解决方案，环境信息如下：

• Ubuntu 22.04
• Ansible 2.10.8

执行的Ansible剧本内容：

- hosts: %remoteSwitch%
  vars:
    - firmware_image_name: "test.txt"
  tasks:
    - name: Copying image to the switch... This can take time, please wait...
      net_put:
        src: "/etc/ansible/firmware_images/C2960X/{{  firmware_image_name  }}"
        dest: "flash:{{  firmware_image_name  }}"
      vars:
        ansible_command_timeout: 20
        protocol: scp
