Description

Webhook listener does trigger only if endpoint url in not empty, i.e. it's not possible to configure listener on / url.

Example code:

- name: example webhook
  hosts: all
  sources:
    - ansible.eda.webhook:
        host: localhost
        port: 5000

  rules:
    - name: trigger when meta is defined
      condition: event.meta is defined
      action:
        debug:

Execute:

ansible-rulebook --rulebook example.yml -i hosts.yml --verbose

What I Did

Example requests:

> curl -d "{\"data\": \"example\"}" http://localhost:5000/someurl 
webhook

Ansible-rulebook outputs:

INFO:aiohttp.access:127.0.0.1 [21/Nov/2022:17:39:41 +0000] "POST /someurl HTTP/1.1" 200 158 "-" "curl/7.79.1"

When I make request to root url:

> curl -d "{\"data\": \"example\"}" http://localhost:5000/       
404: Not Found

Ansible-rulebook log outputs:

INFO:aiohttp.access:127.0.0.1 [21/Nov/2022:17:41:03 +0000] "POST / HTTP/1.1" 404 173 "-" "curl/7.79.1"
