when i modify naming instance got error ,codes:

self.client = nacos.NacosClient(server_addresses=self.host, 
                                namespace=self.namespace,
                                username=self.username,
                                password=self.password)


  self.client.add_naming_instance(service.service_name, service.host, service.port, 
                                  weight=service.weight,
                          metadata=service.to_dict(),
                          enable=service.is_healthy,
                          group_name=self.group, cluster_name=self.cluster,heartbeat_interval=service.heartbeat_interval)
  self.client.modify_naming_instance(service.service_name, service.host, service.port)

add_naming_instance works fine ,but when i modify ,get error:

  File "/Volumes/Codes/*/*/utils/nacos_util.py", line 36, in add_service
    self.client.modify_naming_instance(service.service_name, service.host, service.port)

应该是你的config命名空间和discover命名空间不一致导致的
