Delegate_to: localhost is not working as expected

Hello @bcoca , thanks for the response , and this is the output

ansible-inventory --host localhost
[WARNING]: No inventory was parsed, only implicit localhost is available
{
    "ansible_connection": "local",
    "ansible_python_interpreter": "/usr/bin/python3"
}

And looks like this is working as expected and getting executed in the localhost. But Can you please help me with the below because it is a blocker as of now for me.
