Quarkus reactive rest client @HeaderParam("Authorization") not working and how to debug

Question

In my Quarkus app, I need to make ah http request to another server, in which the Authorization value needs to be passed.

I am using the reactive rest client and tried to use the @HeaderParam("Authorization") to customize the header:

@Path("/api")
@ApplicationScoped
@RegisterRestClient
@RegisterProvider(value = RestClientExceptionMapper.class)
public interface InternalService {
  @POST
  @Path("/xxx")
  @Produces({APPLICATION_JSON})
  @Consumes({APPLICATION_JSON})
  Uni<List<String>> Abc(
      @HeaderParam("Authorization") String bearerVal,
      List<String> values);
}

It does not work.

On the client side, I can confirm that the bearerVal is correctly set Bearer xxx.

On the server side, I can confirm that the request is received, but the Authorization header value is not set.

I wonder what is missing here? How can I debug the header values used by the the underlying http client?

Which version of Quarkus are you using?

If you use version 2.5 or newer, you can enable logging requests and responses with:

quarkus.rest-client.logging.scope=request-response
quarkus.log.category."org.jboss.resteasy.reactive.client.logging".level=DEBUG

For more details, see the Logging traffic section in the REST Client Reactive guide.
