Changed signature to use some_id instead of tradeskill
Changed error logging to use actual function name
Changed query to use containers (type and some_id) instead of just one or the other - this helps simplify recipes

Changed signature from using tradeskill to using some_id
Changed query to use containers instead of tradeskill
Changed error message posting to use actual name of function
Changed fetch results to include tradeskill from recipe in spec
