Spring WebSocket引发MessageDeliveryException，原因是：java.lang.UnsupportedOperationException:null

当我使用SimpMessageTemplate转换并发送消息时，spring websocket引发以下异常：

WebSocket配置

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {
    public static final String WS_STOMP_ENDPOINT_SERVER = "/riten_ws_server";
    public static final String WS_STOMP_ENDPOINT_CLIENT = "/riten_ws_client";
    public static final String WS_TOPIC_PREFIX = "/riten_ws_topic";
    public static final String WS_ORG_TOPIC = "/org";

    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.enableSimpleBroker(WS_TOPIC_PREFIX + WS_ORG_TOPIC);
        config.setApplicationDestinationPrefixes(WS_STOMP_ENDPOINT_CLIENT);
    }

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint(WS_STOMP_ENDPOINT_SERVER).setAllowedOrigins("*").withSockJS();
    }

控制器

@Controller
public class WSController {
    @Autowired
    private SimpMessagingTemplate template;
    
    @GetMapping("/ws/reply")
    public String msgReply(@RequestParam String msg) {
        System.out.println(msg);
        template.convertAndSend(WebSocketConfig.WS_TOPIC_PREFIX + WebSocketConfig.WS_ORG_TOPIC, msg);
        return msg;
    }

安全配置

security:
  oauth2:
    client:
      client-id: ENC(wLUFiQm3+mYpuFOuxSus/A==)
      client-secret: ENC(wLUFiQm3+mYpuFOuxSus/A==)
      scope: server
      ignore-urls:
        - /actuator/**
        - /v2/api-docs
        - /swagger-ui.html/**
        - /webjars/**
        - /swagger-resources/**
        - /riten_ws_server/**
    resource:
      loadBalanced: true
      #      token-info-uri: http://${AUTH-HOST:riten-crc-auth}/oauth/check_token
      token-info-uri: http://192.168.0.249:31300/auth/oauth/check_token

附言： 1、 我确信前端websocket客户端已经连接到websocket服务器； 2、 WSController在springboot应用程序中，同时通过SpringCloudGateway连接到eureka，但我没有在gateway中添加任何websocket配置
