why the kubernetes give tips unknown resource kind: DaemonSet when deploy

When I using this yaml to deployment traefik 2.6.1 in kubernetes v1.15.2(this yaml file also copied from kubernetes v1.15.2 cluster):

Daemonset has been moved to apps/v1 from extensions/v1beta1 Kubernetes version 1.16.

https://kubernetes.io/blog/2019/07/18/api-deprecations-in-1-16/

You can check the kubernetes version used using kubectl version

To check the api versions available use below command

kubectl api-resources | grep daemonset
daemonsets                        ds           apps                           true         DaemonSet
