OS / Environment

Juniper MX960 running JUNOS 20.4R3-S3.4

Summary

1. Bug occurs regardless of Python versions tested (3.7, 3.8, 3.9, 3.10)
2. Bug occurs upon installation of ansible-core version 2.12.9 or greater
3. Bug only occurs while using 'juniper.device.pyez' connection type. 'local' connection type works as expected.

Steps to reproduce

- name: backup, configure, rollback
  hosts: acm-lab-core1.custcbb.local
  collections:
    - juniper.device
  connection: juniper.device.pyez
  gather_facts: no
  tasks:
    - juniper.device.config:
        check: false
        commit: false
        dest: "backup/{{ lookup('pipe','date +%Y-%m-%d-%H-%M-%S') }}_{{ inventory_hostname_short }}.config"
        diff: false
        retrieve: "committed"

Expected results

For the juniper.device.config task to execute successfully and report an "ok" status

Actual results
