This question was asked a while ago, recording the answer here for anyone else with the same problem.

If you are passing a rapidjson::Document into a function, try passing by reference. i.e. instead of void doSomething(rapidjson::Document doc) write void doSomething(rapidjson::Document &doc). I think there is an issue with using the rapidjson::Document copy constructor.
