> Key: CAMEL-26550
> URL: https://issues.apache.org/jira/browse/CAMEL-26550
> Project: Camel
> Issue Type: Bug
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 4.22.3, 4.24.0
>
>
> Found while fixing CAMEL-26515 (PR #29112).
> {{GrpcConsumer}} accepts {{consumerStrategy=PROPAGATION}} together with
> {{routeControlledStreamObserver=true}}. For client and bidi streaming calls,
> {{GrpcRequestPropagationStreamObserver}} (lines 41 and 61) never sets the
> {{grpcResponseObserver}} exchange property, and still sends the route body as
> the reply itself. So a route that uses the
> {{toRouteControlledStreamObserver}} producer fails (no response observer),
> and the reply is not controlled by the route.
> The docs say to use {{DELEGATION}} for a route-controlled stream observer.
> Options:
> * reject the combination when the consumer starts, with a clear message
> pointing to DELEGATION (recommended), or
> * support it: set the property and do not send the body in the propagation
> observer.
