Server:

// SocketBrokerConfig.java

@Configuration
@EnableWebSocketMessageBroker
class SocketBrokerConfig : WebSocketMessageBrokerConfigurer {

    override fun configureMessageBroker(registry: MessageBrokerRegistry) {
        registry.enableSimpleBroker(
            LoginController.RESPONSE,

        registry.setApplicationDestinationPrefixes("/server")

    override fun registerStompEndpoints(registry: StompEndpointRegistry) {
        registry.addEndpoint(LoginController.URI).setAllowedOrigins("http://localhost:3000").withSockJS()
    }
}


@Controller
class LoginController(
    private val msgTemplate: SimpMessagingTemplate,

    @MessageMapping("/server/login")
    fun handle(
        @Payload request: LoginRequest,
        @Header("simpSessionId") sessionId: String,
    ) {
        println("LoginController : $sessionId")
        msgTemplate.convertAndSend("/player/login", LoginResponse("TEST"))
    }

}

data class LoginRequest(
    val username: String,
)

data class LoginResponse(
    val token: String,
)

Browser lient:

import SockJS from "sockjs-client";
import {Stomp} from "@stomp/stompjs";


      const socket = new SockJS('http://localhost:8080/server/login');
      const stompClient = Stomp.over(socket);
      stompClient.connect({}, () => {
          let url = stompClient.ws._transport.url;
          console.log({url});
          url = url.replace(
              "ws://localhost:8080/server/login/",  "");
          url = url.replace("/websocket", "");
          url = url.replace(/^[0-9]+\//, "");
          console.log("Your current session is: " + url);

          stompClient.subscribe('login', (msg) => {
              console.log({msg});
          })
          stompClient.send('/server/login', {}, JSON.stringify({ username: 'TEST' }))
          stompClient.send('server/login', {}, JSON.stringify({ username: 'TEST' }))
          stompClient.send('/login', {}, JSON.stringify({ username: 'TEST' }))
          stompClient.send('login', {}, JSON.stringify({ username: 'TEST' }))
      })

And the console output:

But there is not response from server, and also nothing in server console (there is println in controller)

It's my first time with Stomp, Spring Boot Websockets and SockJS I understand how TCP works, but I don't understand what rule I'm breaking here that this is not working :(

Please help
