> camel-grpc - the consumer sends the reply without checking it against the
> method response type: an unchanged request is decoded by the client as the

> Key: CAMEL-26187
> URL: https://issues.apache.org/jira/browse/CAMEL-26187
> Project: Camel
> Issue Type: Bug
> Components: camel-grpc
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 4.24.0
>
>
> Found while adding the catalog body types of grpc (CAMEL-24961, PR #28413).
> h4. 1. The consumer reply is not checked against the response type
> {{GrpcMethodHandler}} (main 2a465aa4814c, line 71 to 77) passes the body
> after the route to {{responseObserver.onNext}} as is. When the route leaves
> the request body unchanged, the {{PingRequest}} is serialized and the client
> decodes the bytes as a {{PongResponse}}: no error, a response with wrong
> field values. A body of any other class is sent the same way. Checked on
> 4.24.0-SNAPSHOT with an embedded gRPC netty server with a Camel consumer on
> localhost.
> Proposed: convert the reply to the response type of the method (mandatory),
> and fail the call with a status error when it is not that type.
