I am trying to use On_delete event but not works.
Screenshot issue: https://imgur.com/SMV47hR
In screenshot I can see that it does not have field ticket_id in parameters for event handler.
The delete event only get the key field as delete row id. You need to fetch rest data using this id and then use in your code.
