Ansible: 'ping' Fortigate host results into error 'Unknown action 0' - ansible

Question

I'm new to Ansible and I'm running into errors. My goal is to be able to manage Fortigate/Cisco devices.
I created a Ubuntu VM(22.04) with all the necessary packages needed to run Ansible. I've created a very basic hosts file with a firewall group:
[firewalls]
10.23.60.120
10.23.60.122
I've been successful at pinging each of the firewalls as well as using SSH to connect to the firewalls. But once I attempt to ping the firewalls using the -m ping module I get the following errors:
ansible -i hosts firewalls -m ping
[WARNING]: Platform unknown on host 10.23.60.120 is using the discovered Python
interpreter at /usr/bin/python, but future installation of another Python
interpreter could change the meaning of that path. See
https://docs.ansible.com/ansible-
core/2.13/reference_appendices/interpreter_discovery.html for more information.
10.23.60.120 | FAILED! => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python"
}
"changed": false,
"module_stderr": "Shared connection to 10.23.60.120 closed.\r\n",
"module_stdout": "TR1-SDWAN-LAB-01 # 8415: Unknown action 0\r\nCommand fail. Return code
-1\r\n\r\n TR1-SDWAN-LAB-01 # ",
"msg": "MODULE FAILURE\nSee stdout/stderr for the exact error",
"rc": 0
}
Any help is appreciated.

According the information provided it seems that you try to establish a SSH connection to a switch. Such devices may not have all capabilities for Python scripts.
Because of ping module – Try to connect to host, verify a usable python and return pong on success it
"is NOT ICMP ping, ... just a trivial test module that requires Python on the remote-node"
is a "... test module, this module always returns pong on successful contact. It does not make sense in playbooks, but it is useful from /usr/bin/ansible to verify the ability to login and that a usable Python is configured."
The Most Significant Information is the error message Unknown action 0 and which is according Fortigate Documentation - Command syntax just an unknown command
"If you do not enter a known command, the CLI will return an error message such as: Unknown action 0"
