It would help a lot if you explain what your model object looks like, and at

The current mapping for the id and version fields for every table in

It looks like your query does not return Organization entity, as some
properties are missing. See:

You could also try using AddScalar instead of AddEntitiy, and then load
those Organizations based on the keys returned by your query. (This
