Error obtaining Endpoints for Service

Question

W0721 01:33:53.638642 6 controller.go:812] Error obtaining Endpoints for Service "dev1/nginx-service1": no object matching key "dev1/nginx-service1" in local store
W0721 01:33:53.638672 6 controller.go:812] Error obtaining Endpoints for Service "dev1/tomcat-service1": no object matching key "dev1/tomcat-service1" in local store

下面查看了service和endpoints，都是正常的呀，不知道为啥会报错。

[root@k8smaster ingress-controller]# kubectl get svc -n dev1
NAME              TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)    AGE
nginx-service1    ClusterIP   None         <none>        80/TCP     19m
tomcat-service1   ClusterIP   None         <none>        8080/TCP   19m

[root@k8smaster ingress-controller]# kubectl get endpoints -n dev1
NAME              ENDPOINTS                             AGE
nginx-service1    10.244.1.103:80,10.244.2.119:80       25m
