Hi @aep_guy ,
Data prep in datastream requires mapping for _id and timestamp fields always to be there as these are required fields of the ExperienceEvent class. This is the reason that when you start with data prep these two mappings are already there as below,

The error you got would occur if _id mapping was removed. Can you confirm if that is the case or the error occurs even when _id mapping is added?
