Description

I'm trying to use ribbon load balancer in Karaf like this:

        from("timer:consumerTimer?fixedRate=true&delay=0&period=10000")
                .routeId("consumeService")
                .setBody(simple("Hello, Producer! This is message from consumer on ${camelId}/${routeId}"))
                .serviceCall()
                    .name("producer")
                    .component("netty4:tcp")
                    .ribbonLoadBalancer()
                    .consulServiceDiscovery()
                    .endParent()
                .convertBodyTo(String.class)
                .log("Producer response: ${body}");

But after start my bundle, following error appear in log (log:display):
