It seems that both example failures are missing all the methods (and hence causing the exception). The printout comes from https://github.com/cms-sw/cmssw/blob/5cc0e67f56fdf5cf3b0126da9b378733083ae17f/CommonTools/Utils/src/MethodSetter.cc#L127-L133 The loop uses these functions https://github.com/cms-sw/cmssw/blob/5cc0e67f56fdf5cf3b0126da9b378733083ae17f/FWCore/Reflection/src/TypeWithDict.cc#L880-L889 `IterWithDict` is essentially...

FYI @cms-sw/alca-l2 @cms-sw/hcal-dpg-l2

Does the IOV of `IdealMagneticFieldRecord` change between runs 352567 and 352568? Looking at its definition https://github.com/cms-sw/cmssw/blob/86937de21338aa5477a0405b3ebb082811bcbd7e/MagneticField/Records/interface/IdealMagneticFieldRecord.h#L11-L13 `RunInfoRcd` sounds like something whose IOV could change for every Run. Could it be...
