Webhook event people.registered response discrepancy

Hi !

We are currently using the people.registered event to trigger a webhook from our app.
But it seems that the response we get from this event is different from what is specified in your documentation (https://developers.livestorm.co/docs/webhooks-1#peopleregistered).
Did I miss something?
Here is an example of the response we get from the event :
