Blocked vertx threads

I must learn to develop microservices using:

And as an IDE I am using Intellij

The code I'm working on is this:

import io.vertx.core.AbstractVerticle;
import io.vertx.core.Future;
import io.vertx.core.Promise;
import io.vertx.core.Vertx;
import io.vertx.core.http.HttpServer;
import io.vertx.core.json.Json;
import io.vertx.core.json.JsonObject;
import io.vertx.ext.mongo.MongoClient;
import io.vertx.ext.web.Router;
import io.vertx.ext.web.RoutingContext;
import io.vertx.ext.web.handler.BodyHandler;

public class MainVerticle extends AbstractVerticle {

    MongoClient mongoSharedClient = null;

    private Future<Void> prepareDatabase(){

        Promise<Void> promises = Promise.promise();

        JsonObject config = Vertx.currentContext().config();

        String uri = config.getString("mongo_uri");

        if(uri == null){
            uri = "mongodb://localhost:27017";

        }

        String database = config.getString("mongo_db");
        if (database == null){
            database = "test";
        }

        JsonObject configMongo = new JsonObject();

        configMongo.put("connection_string", uri);
        configMongo.put("db_name", database);

        mongoSharedClient = MongoClient.create(vertx, configMongo);

        if(mongoSharedClient != null){
            promises.complete();
        }else {
            promises.fail("Error in Database");
        }

        return promises.future();
    }

    @Override
    public void start(Promise<Void> startFuture) throws Exception {

        prepareDatabase().compose(as-> HttpServer()).onComplete(asyn->{
            if(asyn.succeeded()){
                startFuture.complete();
            }else {
                startFuture.fail("Error");
            }
        });
    }

    private Future<Void> HttpServer(){
        Promise<Void> promises = Promise.promise();

        HttpServer server = vertx.createHttpServer();
        Router router = Router.router(vertx);

        router.get("/test/").handler(this::pruebaRuta);
        router.post("/create/").handler(this::createPrueba);
        router.post().handler(BodyHandler.create());

        server.requestHandler(router).listen(9090, ar -> {
            if(ar.succeeded()){
                promises.complete();
            }else {
                promises.fail(ar.cause());
            }
        });
        return promises.future();
    }

    private void createPrueba(RoutingContext routingContext) {
        JsonObject data = routingContext.getBodyAsJson();
        mongoSharedClient.insert("User", data, result -> {
            if(result.succeeded()){
                routingContext.response().setStatusCode(200).putHeader("Content-Type", "text/html").end("Operation Successful");
            }else {
                routingContext.response().setStatusCode(400).putHeader("Content-Type", "text/html").end(result.cause().getMessage());
            }
        });
        routingContext.response().setStatusCode(200).putHeader("Content-Type", "Application/Json; charset=utf-8").end(Json.encodePrettily(data));
    }

    private void pruebaRuta(RoutingContext routingContext) {

        routingContext.response().setStatusCode(200).putHeader("Content-Type", "text/html").end("Success Execute!");

    }

}

At the moment I only want to do small tests with postman, the problem is that when I run the project I get the following:

In postman I try to test the route localhost:9090/create/ and it returns error 500

I know the question is long, but seriously I don't know what to do, I have looked for a solution but the truth is that I don't really understand what my mistake is or what is happening, I need your help. Thank you very much

If you look at the middle stacktrace, it is reporting that the host it's trying to reach to connect to the Mongo database rejected the connection. Make sure it is reachable.

I'll bet the 500 error you're seeing is a Null Pointer Exception caused by you trying to use the mongo client even though it failed to initialize and the variable was never assigned.

The first and third stacktrace are complaining that binding to the ports while starting up the server is taking too long. This might be an issue in the underlying netty library.
