@mmiklavc I looked through the validation stuff more, I think that
validation is the way to go here. The grok parser will add invalid message for
each exception, parser failure, and then in the validation call fail those
messages. It will have to be done so that the returned message makes sense
when it is sent to the error topic.
What do you think? @cestella ?---
