Can you double-check your schema to see if you have all the fields required to support nested documents. You are supposed to get away with just _root_, but really you should also include _nest_path and _nest_parent_. Your particular exception seems to be triggering something (maybe a bug) related to - possibly - missing _nest_path_ field.
