on_postload_event_commented webhook task fails with AttributeError: 'dict' object has no attribute 'event_title'

[omarix]

Summary

I set up a webhook for on_postload_event_commented following the documentation. The task fails before sending the request to my endpoint. I’m using a minimal config with use_rendering: false.

Environment

• IRIS: v2.4.19
• Webhooks module (iris-webhooks-module): v1.0.2

Webhook configuration (minimal)

{
  "name": "on_comment",
  "active": true,
  "trigger_on": ["on_postload_event_commented"],
  "verify_ssl": false,
  "request_url": "https://example.com/webhook/on_postload_event_commented",
  "use_rendering": false,
  "request_body": {
    "comments": "comments"
  }
}

Steps to reproduce

1. Register the webhook above.
2. Add a comment on any event in IRIS.
3. Check the task result.

Actual result (error)
