LinuxQuestions.org - [SOLVED] Ansible: redirect stdout AND stderr

To capture output of the command in ansible i use "shell" module.
It works OK as long as the command gives stdout.
However, if the command gives ERROR message, it creates empty file.

Eg. executing: systemctl status iptables on the system without "iptables.service" installed should display: "Unit iptables.service could not be found"

Unfortunately, ansible shell module does not redirect this msg and creates empty file.
Is there a way to redirect also error output to the file?
Below my code

Code:

- hosts: all

  become: yes



  vars:

    extensionForOriginalFile: ORIG

    extensionForBackupFile: "{{ lookup('pipe', 'date +%Y%m%d-%H%M%S') }}"



  tasks:

  - name: dump the iptables status

    shell: "systemctl status iptables > /tmp/iptables.txt"

    ignore_errors: yes



  - name: copy the files from the remote server

    fetch:

      src: "{{ item }}"

      dest: "/home/output/"

    with_items:

      - "/tmp/iptables.txt"

    args:

      removes: "{{ item }}"
