Как springboot-rsocket получает несколько параметров?

private final RSocketRequester rSocketRequester;

@RequestMapping(path = "/**")
public Publisher<ServerResponse> mockController(ServerWebExchange serverWebExchange) {
    String path = serverWebExchange.getRequest().getPath().toString();
    String method = serverWebExchange.getRequest().getMethodValue();
    return rSocketRequester.route("/mock").data(path).data(method).retrieveMono(ServerResponse.class);
}


@MessageMapping(value = "/mock")
public Mono<ServerResponse> mockService(String path, String method) {
    return Mono.just(new ServerResponse<>(0, "success", path+method));
}

Если я задаю дополнительные параметры для Rsocket, Rsocket сообщает об ошибке, когда я запрашиваю контроллер

, как его восстановить? Это мой конфиг rsocket-controller, это может быть проблема конфигурации? 

@Bean
RSocket rSocket() {
    return RSocketFactory
            .connect()
            .dataMimeType(MimeTypeUtils.ALL_VALUE)
            .frameDecoder(PayloadDecoder.ZERO_COPY)
            .transport(TcpClientTransport.create(7003))
            .start()
            .block();
}

@Bean
RSocketRequester rSocketRequester(RSocketStrategies rSocketStrategies) {
    return RSocketRequester.builder()
            .rsocketFactory(factory -> factory
                    .dataMimeType(MimeTypeUtils.ALL_VALUE)
                    .frameDecoder(PayloadDecoder.ZERO_COPY))
            .rsocketStrategies(rSocketStrategies)
            .connect(TcpClientTransport.create(7003))
            .retry().block();
}
