How to debug(maybe worthy a trouble shooting doc) on Application lifecycle management

[jichenjc]

Follow https://open-cluster-management.io/getting-started/integration/app-lifecycle/

and now at last step

kubectl get subscriptions.apps --context ${CTX_MANAGED_CLUSTER}

but nothing show out

# kubectl get subscriptions.apps --context  kind-cluster1
No resources found in default namespace.

checked the pod status seems fine, logs show some suspect issue but not sure it's root cause..

# kubectl get pods -A --context kind-hub
