Reporter: changzhiwin
I write some Camel demo, about proxy of grpc.
When use query parameter of routeControlledStreamObserver (official website),
some special manners tack place.
When using stream mode, the response observer is null, and I don't know why?
there is the full project at github(https://github.com/changzhiwin/grpc-test).
And I use this client to test camel project.
$ git clone -b v1.41.0 https://github.com/grpc/grpc-java.git
And I asked at
https://stackoverflow.com/questions/69765267/why-response-observer-is-not-exist-in-consumer-of-camel-grpc-componet.
