By default, the serializer uses the
useActualTypeOnSerialize: trueparameter, which ensures that the actual runtime type of the message is used during serialization. This is important for polymorphic message types where you might publish a derived type but declare the producer with a base type.If this is not the default STJ does only include the base type properties (unlike Newtonsoft.Json).
