@this looks to be related to https://scaledb.atlassian.net/browse/FOGL-9280 which looks to have been caused by mismatched versions. Where did you get the various components you used for testing?

I've tracked this down further and it is a bug in the batch-label filter. It is not returning valid JSON.

@MarkRiddoch / @firozalikhan yes it is a know issue in batch-label filter. I would raise a patch today

Have just checked this does not happen with south/north.

With the PR ((https://github.com/dianomic/foglamp-filter-batch-label/pull/2)) also, adding "Sigma-cleanse" after "batch-label" "Dispatcher service" crashes. Even when the Control Pipeline is disabled.
