Hi,
You are send the protocolbuf dataformat , not marshalling or
unmarshalling the objects.
Please check out this unit test[1] of camel protocol buffer as an example.

I get this error!

How I can make this test work ? My first target is manipulate the
ProtocolBuffer inside a processor and not get in a unmarshal or

Thanks.
