How reproducible:

always

Steps to Reproduce:
1. dnf install -y squid
2. Create the playbook:
[root@node-0000247513 ~]# cat test.yml 
- hosts: localhost
  tasks:
    - service:
        name: squid
        state: started
        enabled: true
      become: true
3. Run the Playbook

[root@node-0000247513 ~]# ansible-playbook -vv test.yml 
ansible-playbook 2.9.10
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3.9/site-packages/ansible
  executable location = /usr/bin/ansible-playbook
  python version = 3.9.0b3 (default, Jun 10 2020, 00:00:00) [GCC 10.1.1 20200507 (Red Hat 10.1.1-1)]
Using /etc/ansible/ansible.cfg as config file
[WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match 'all'

[root@node-0000247513 ~]# systemctl status squid

Actual results:

Playbook failed and service not started.

Expected results:

A service started and a playbook success.

Additional info:

Looks like systemctl show <service> is used by the ansible module. I see that on my test node the command return 1 + the expected content + an error line. See below:

[root@node-0000247513 ~]# systemctl --no-pager show squid                                                                                     
Type=notify
