Sysdig doesn't record events inside kubernetes pods

I use Microk8s kubectl. I tried to record events inside a pod (e.g., mypod) using sysdig by setting a filter k8s.pod.name=mypod. But sysdig does not log any event.

p.s. I can get the events inside docker containers (not in pods) using sysdig while setting the filter container.name=mycontainer.

I would appreciate any possible explanation/solution about this.
