Failed json lines being ignored

Thanks @kvch but the pid was just an example, I have no idea what field and values our users can send, so I just don't want to lose these lines if they do some mess.
I could find someone else with the same problem here Ingest pipeline errors and "on_failure" and turns out that the on_failure is not triggered because the problem is not on the processor side.
I'll create a topic there later, thanks anyway :slight_smile:
