Oban telemetry event `[:oban, :engine, :discard_job, :exception]` not emitted
It says in the Oban documentation that a [:oban, :engine, :discard_job, :start | :stop | :exception] is emitted by the Oban library,
I attach an event handler
[
"oban-job-discard-handler",
[:oban, :engine, :discard_job, :exception],
&handle_job_discard/4,
%{}
]
|> Enum.each(fn [handler_id, event_name, function, config] ->
:telemetry.attach(handler_id, event_name, function, config)
end)
But it seems like that event is never emitted by Oban, am I missing something? Any help would be much appreciated

The state field will indicate if it was an error, or if it was the final error and the job is being discarded. There’s information about all the fields in the Job Events section.

The :discard_job event is only triggered by direct Engine calls. You can handle discards with [:oban, :job, :exception].
Side note; if you’re handling multiple events, use :telemetry.attach_many
