Kubernetes for the Absolute Beginners - Service Labs

The last task inside the k8s service lab seems to be broken, using the following service definition:

apiVersion: v1
kind: Service
metadata:
  name: webapp-service
spec:
  type: NodePort
  ports:
    - targetPort: 8080
      port: 8080
      nodePort: 30080
  selector:
    name: simple-webapp

No application is shown when opening the simple-webapp-ui tab, please check the lab again.

can you share image of service kubectl describe svc webapp-service
