Enable Apache site using Ansible

问题

I am running a playbook from a python script. I am following this code

The following command works perfectly.

ansible -i path/to/inventory.yml host_name -m command -a"a2ensite site_name"

But when I try to do the same by executing a playbook from the python script. It says the site doesn't exist. Following is the playbook.

playbook = dict(
        name = "Enable Site",
        hosts = ['token_server'],
        gather_facts = 'no',
        tasks = [
            dict(action=dict(module='command', args="a2ensite " + site_name), register='shell_out'),
            dict(action=dict(module='service', args="name='apache2' state='reloaded'"), register='shell_out'),
        ]
    )

It gives the following error.

fatal: [token_server]: FAILED! => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"}, "changed": true, "cmd": "a2ensite token_server", "delta": "0:00:00.054682", "end": "2019-12-11 01:03:10.546478", "msg": "non-zero return code", "rc": 1, "start": "2019-12-11 01:03:10.491796", "stderr": "ERROR: Site token_server does not exist!", "stderr_lines": ["ERROR: Site token_server does not exist!"], "stdout": "", "stdout_lines": []}

Update I tried running this playbook.

playbook = dict(
        name = "Enable Site",
        hosts = ['token_server'],
        gather_facts = 'yes',
        tasks = [
            dict(action=dict(module='shell', args='ls /etc/apache2/sites-available'), register='shell_out'),
        dict(action=dict(module='debug', args=dict(msg='{{shell_out.stdout}}')))
        ]
    )

It shows the contents of /etc/apache2/sites-available directory on my local. It means the command is actually being executed on my local, not on the remote server.

Here is my "hosts inventory file".

all:
  hosts:
    policy_server:
      ansible_host: 155.138.130.72
      ansible_password: XXXXXXXXXX
      ansible_ssh_common_args: -o StrictHostKeyChecking=no
      ansible_user: root
    token_server:
      ansible_host: 155.138.150.239
      ansible_password: XXXXXXXXXX
      ansible_ssh_common_args: -o StrictHostKeyChecking=no
      ansible_user: root
