> Headers that are added to the Message in the camel Exchange before making a call to the camel-grpc component are not received at the grpc consumer. The expectation is that these headers would be added to the grpcStub before sending over the wire (like other components like http4 etc).
> Our team has come up with a workaround for this but it is extremely cumbersome. We had to extend the GrpcProducer to introduce a custom GrpcExchangeForwarder that would copy header from exchange to the stub before invoking the sync/async method.
> At the consumer side we had to extend the GrpcConsumer to use a custom ServerInterceptor to capture the grpc headers and custom MethodHandler to transfer the grpc headers to the Camel exchange headers.
