I'm trying to connect my react.jsocks client to my spring boot backend web sockets but I can't connect them, it's giving me some errors on the chrome console like this:

chrome console error

I don't have any errors in my Spring Boot part, but there are some warnings like:

Spring Boot Console

Why can't I connect them? My react.js part looks like this:

      }
    }
              
export default connect(mapStateToProps,mapDispatchToProps) (Login);

And my Spring Boot configuration class:

package com.project.blog.websocket;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.messaging.simp.config.MessageBrokerRegistry;
import org.springframework.web.socket.config.annotation.EnableWebSocketMessageBroker;
import org.springframework.web.socket.config.annotation.StompEndpointRegistry;
import org.springframework.web.socket.config.annotation.WebSocketMessageBrokerConfigurer;

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfiguration implements WebSocketMessageBrokerConfigurer {

    @Value("${blog.app.front}")
    private String url;
    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/wss").setAllowedOrigins(url).setAllowedOriginPatterns("*").withSockJS();
    }

    @Override
    public void configureMessageBroker(MessageBrokerRegistry registry) {
        registry.setApplicationDestinationPrefixes("/app");
        registry.enableSimpleBroker("/user-connect");
        registry.setUserDestinationPrefix("/user");
    }


}

Similarly for the network socket controller I wrote this part:

package com.project.blog.websocket;

import com.project.blog.entities.User;
import com.project.blog.repositories.UserRepository;
import com.project.blog.responses.ErrorSuccessResponse;
import lombok.RequiredArgsConstructor;
import org.springframework.messaging.handler.annotation.MessageMapping;
import org.springframework.messaging.simp.SimpMessagingTemplate;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Controller;

import java.time.LocalDateTime;
import java.util.LinkedList;
import java.util.List;

@Controller
@RequiredArgsConstructor
public class WebSocketController {


    private final SimpMessagingTemplate simpMessagingTemplate;
    private final UserRepository userRepository;

    @MessageMapping("/message")
    private ErrorSuccessResponse receiveMessage(String user){
        ErrorSuccessResponse errorSuccessResponse = new ErrorSuccessResponse();
        errorSuccessResponse.setError("block oldu");
    simpMessagingTemplate.convertAndSendToUser(user,"/private",errorSuccessResponse);
    return errorSuccessResponse;
    }
    @Scheduled(fixedDelay = 1000)
    private void checkBlocks(){
        LocalDateTime now = LocalDateTime.now();
        List<User> users = userRepository.findBlockedUsers(now);

        users.stream().forEach(user->{
            receiveMessage(user.getUsername());
        });
    }
}

I try to use socks to connect my react.js frontend and spring boot backend but I can't do it

My process.env.REACT_APP_ROOT_URL is: http://localhost:1998 and @Value("${blog.app.front}") Private string url; the value of this part is: http://localhost:3000
