juniper_junos_software installs software but task fails due to "No handlers.."

Question

Im trying to install 12.3X48-D70 on an SRX550 using the juniper_junos_software module, and while it successfully installs and reboots the device the task returns as failed because of a "No handlers" errors.

Playbook:

- name: Upgrade Juniper devices
  juniper_junos_software:
    host: "{{ inventory_hostname }}"
    local_package: "junos-srxsme-12.3X48-D70.3-domestic.tgz"
    reboot: yes
    version: "12.3X48-D70.3"
    user: user
    passwd: "{{ secret }}"
    port: 22
  ignore_errors: True
  register: junos_upgrade
  when: junos_before|success

Verbose output:

TASK [code_upgrade : Upgrade Juniper devices] ***********************************************************

    "module_stdout": "",
    "msg": "MODULE FAILURE",
    "rc": 1

The error shows up shortly after the device initiates a reboot and goes offline. I do not have this problem with any of the other juniper modules.

Im running Ansible 2.4.2, junos-eznc 2.1.8, python 2.7.5, and the Juniper.junos role is 2.1.0

Someone already reported such problem to the developers of Junos, it seems you are hit by bugs https://github.com/Juniper/ansible-junos-stdlib/pull/361 and https://github.com/Juniper/py-junos-eznc/issues/651.

However the fix is present in the release 2.1.0 of ansible-junos-stdlib (the one you have) so it is not clear to me if this is the same bug or another closely related.

The best way to solve this is to contact the developers to report the issue on Github, to confirm this is the same bug or another and make it fixed.
