Collecting results from pipeline execution snap

Hi,

I have tested a bit more. If I force an error in e.g. Mapper3 or LogMessage (see picture below), I see the child-error-pipeline getting executed fine. Only, when I force an error in JSON Formatter Snap, it fails with the error message mentioned in the initial post.
Is it a BUG or a FEATURE, that JSON Formatter does not call error pipeline properly? Are there other snaps with this FEATURE?

I also noticed, that the child-error-pipeline only gets executed once, for all the errors in the pipeline, WOW-1!
What is more, even if errors occured in more snaps, pipeline gets executed further, and I see “Completed” status in the Dashboard, WOW-2! ← this probably is why, error pipeline gets executed only once. Is there a possibility to force the pipeline to stop on error and use error pipeline?

cheers
Simon 🙂
