      The other SciPi error I saw was

      ValueError: Error in inputs to MergeCoaddMeasurements: source IDs do not match 

      But if I try to reproduce it directly, I'm seeing

      File "/software/lsstsw/stack_20190330/stack/miniconda3-4.5.12-1172c30/Linux64/pipe_tasks/18.0.0-7-g4840a288+1/python/lsst/pipe/tasks/mergeMeasurements.py", line 298, in run
          mergedCatalog.reserve(len(orderedCatalogs[0]))
       IndexError: list index out of range 

      This affects 19/79 quanta.  An example of one that failed is at

      /project/hchiang2/bps/submit/G3M19c/000001/drp/025/input/mmt/quantum083381.pickle 

      That's (tract=9615 patch=77).
