Description

If there is a type error, ArrayFromJSON returns an error message like "Invalid: Expected unsigned int or null, got JSON type 4", where JSON type 4 is a value of type rapidjson::Type enum. It is better to print type names rather than enum values such as "Invalid: Expected unsigned int or null, got JSON type array".
