I want to add (because I learned that the hard way) that you should always transform your “bool” variable with the bool filter in the playbook. If one day you decide to use AWX/AAP, your variable will always be a string even if you thought you send a bool.

So the correct way to write your line:

```yml
when: use_handler is true

```

is:

```yml
when: use_handler | bool is true

```

Or even better (and supported since Ansible 2.10):

```yml
when: use_handler is truthy(convert_bool=True)

```

From the documentation: [Tests — Ansible Documentation](https://docs.ansible.com/ansible/latest/playbook_guide/playbooks_tests.html#testing-truthiness)
