Post request response using Camel Netty4 - HTTP operation failed invoking

I'm new to Camel and am trying to get a response from a Netty4 route using a POST request. I'd like to send a JSON and return a string extracted from the body.

My rest setup is as follows:

public class Server extends RouteBuilder {

    @Override
    public void configure() {

        String listenAddress = "0.0.0.0";
        int listenPort = 8080;

        restConfiguration()
                .component("netty4-http")
                .scheme("http")
                .host(listenAddress)
                .dataFormatProperty("prettyPrint", "true")
                .bindingMode(RestBindingMode.auto)
                .port(listenPort);

        rest("/")
                .post()
                .consumes("application/json; charset=UTF-8")
                .to("direct:post");
    }
}

Within my Camel route I'd like to send the message back using:

@Component
public class RestRoute extends RouteBuilder {

    @Autowired
    CamelContext context;

    @Override
    public void configure() {

        from("direct:post")
                .log("New Request")
                .streamCaching()

                .setHeader(Exchange.HTTP_METHOD,constant(org.apache.camel.component.http4.HttpMethods.POST))
                .setBody().jsonpath("$.Text") // extract text from JSON
                .to("http4://0.0.0.0:8080?bridgeEndpoint=true");

However I get the following error: org.apache.camel.http.common.HttpOperationFailedException: HTTP operation failed invoking http://0.0.0.0:8080 with statusCode: 500

I'd appreciate some help!
