hello team,

I encountered following problem.

I tried to call method IMappingService.removeMapping(Norhtbound, eid) [1]. Eid parameter was specified as instanceof SourceDestKey.
Method [1] calls DataStoreBackEnd.removeMapping(mapping) [2] method. Input parameter mapping is constructed through util method DSBEInputUtil.toMapping() [3] which returns Mapping instance where mappingRecord field isnt' set.
Then in method [2] there is call mapping.getMappingRecord().getEid() which will cause NullPointerException because getMappingRecord returns null.
