Hi Andy,

I am trying to catch any error that happens from any processor in my flow.
So adding a PutFile for each and every processor would not be ideal. And I
don't need the data to be transformed into a usable type. I am passing this
data to Logstash as a csv file (so raw data is just fine). Any thoughts?

Thank you,
James
