How do you notify a handler in Ansible based solely on a conditional?

I would like to notify a handler in my role by doing something like this:

- name: Notify handler
  notify: my_handler
  when: this_thing_is_true|bool

But Ansible just whines:

ERROR! no module/action detected in task.

I have tried various wedges, such as:

- name: Notify handler
  meta: noop
  notify: my_handler
  when: this_thing_is_true|bool

But that similarly whines:

[WARNING]: noop task does not support when conditional

Any suggestions?

Please mind that running a task is not enough for an handler to be notified, you also need a task that creates a changed result.

You can achieve a change result on any task with the help of the changed_when option in Ansible.
Then, doing a simple debug could be an option.

The other ideas I had, but that did not really made sense in the end:

• pause: but you cannot pause for less than a second
• assert: but it feels silly to assert the same condition that you also need to put in the changed_that to notify the handler. You can still assert: that=true but it feels equally silly.
• Maybe the most silliest of the ideas I could came with was a fail task with a failed_when: false.
• command: 'true' is maybe less silly, compared to the above, but I am not totally convinced, still

Given the playbook:

- hosts: localhost
  gather_facts: no
  vars:
    this_thing_is_true: true

  tasks:
    - debug:
        msg: 'Notifying handlers'
        # var: this_thing_is_true 
        # ^-- might be an alternative option to msg:
      changed_when: this_thing_is_true  
      notify: 
        - me 

  handlers:
    - name: me
      debug:
        msg: 'I have been notified'

Gives the recap:

PLAY [localhost] **************************************************

TASK [debug] ******************************************************
changed: [localhost] => 
  msg: Notifying handlers

RUNNING HANDLER [me] **********************************************
ok: [localhost] => 
  msg: I have been notified
