URL: https://github.com/apache/apisix/issues/7610#issuecomment-1205998978

   I found that when the ip changed, the following error log is printed:
   ```
   2022/08/05 11:15:24 [error] 61#61: *1995466 [lua] config_etcd.lua:573: failed to fetch data from etcd: failed to check item data of [/SERVICES/apisix/routes] err:property "upstream" validation failed: property "nodes" validation failed: object matches none of the required,  etcd key: /SERVICES/apisix/routes, context: ngx.timer
   2022/08/05 11:15:24 [error] 56#56: *2034285 [lua] config_etcd.lua:573: failed to fetch data from etcd: failed to check item data of [/SERVICES/apisix/routes] err:property "upstream" validation failed: property "nodes" validation failed: object matches none of the required,  etcd key: /SERVICES/apisix/routes, context: ngx.timer
   ```
   
   and the etcd is
   ```
   /SERVICES/apisix/routes/419517589346059237
   {
   	"create_time": 1659581568,
   	"host": "st-b.admin.srv",
   	"id": "419517589346059237",
   	"name": "后台",
   	"status": 1,
   	"update_time": 1659581568,
   	"upstream": {
   		"_discovery_type": "zookeeper",
   		"_service_name": "admin-web",
   		"discovery_type": "zookeeper",
   		"keepalive_pool": {
   			"idle_timeout": 60,
   			"requests": 1000,
   			"size": 320
   		},
   		"nodes": [
   			{
   				"host": "10.167.37.187",
   				"port": 8766,
   				"weight": 100
   			}
   		],
   		"pass_host": "pass",
   		"scheme": "http",
   		"timeout": {
   			"connect": 6,
   			"read": 6,
   			"send": 6
   		},
   		"type": "roundrobin"
   	},
   	"uri": "/*"
   }
   ```
   the same etcd route is is fine at startup.
