  • [ x ] I have searched the issues of this repository and believe that this is not a duplicate.

Environment

  • Dubbo version: 3.0.5
  • Operating System version: k8s/spring boot
  • Java version: jdk11

Steps to reproduce this issue

  1. 在配置文件application.yml中开启探针
  dubbo:
    application:
      name: demo-provider
      qos-enable: true
      qos-accept-foreign-ip: true
  1. 启动应用，此时consumer可以正常调用provider，可以正常返回结果。
  2. 但是，访问以下三个地址 
    curl -v http://localhost:22222/live      # 返回true
curl -v http://localhost:22222/ready  # 报错
curl -v http://localhost:22222/startup #报错

访问http://localhost:22222/ready 异常信息如下：

2022-01-27 12:20:58.515 ERROR 28796 --- [ qos-worker-3-4] o.a.d.q.s.handler.HttpProcessHandler     :  [DUBBO] execute commandContext: org.apache.dubbo.qos.command.CommandContext@1dcc6545 got exception, dubbo version: 3.0.5, current host: 10.33.0.2

这里影响的是运维功能，因为 Probe spi 的 scope 调整造成的
