Spring Boot 3 Webflux with Micrometer Tracing not showing as a one trace in the zipkin dashboard

My Microservices application has 3 different Microservices. many of them have been created with just spring boot (imperative way) but those application's tracings are shown in the dashboard correctly. but I created one Microservice application by using spring boot 3 with webflux. because of using spring boot 3 I had to use micrometer instead of sleuth.

My 3rd application does make a http request to the webflux application. but that trace details I can't see in the dashboard under the same trace. that trace (webflux one) is shown as a separate one in the dashboard. other 3 Microservices' tracing details are available under one trace. but webflux's trace is not.

the pom.xml file and configuration like below.

Main class (according to the doc https://github.com/micrometer-metrics/tracing/wiki/Spring-Cloud-Sleuth-3.1-Migration-Guide )

package com.example.service6;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import reactor.core.publisher.Hooks;

@SpringBootApplication
public class Service6Application {

    public static void main(String[] args) {
        SpringApplication.run(Service6Application.class, args);
        Hooks.enableAutomaticContextPropagation();
    }
}

I tried lots of examples in the website but I was unable to do that. please help me to solve this problem.

Add propagation type in your properties file as b3. because zipkin does support B3.

management.tracing.propagation.type=b3
