How can I get some resources with the event type?

Hi, I'm trying to watch deleting Endpointslice resources.
And my code is like this.

    let endpointslices = Api::<EndpointSlice>::all(client);
    tracing::info!(name=eps.name_any(),obj=?eps,"Reconcile Endpointslice");

    finalizer(
        &endpointslices,
        ENDPOINTSLICE_FINALIZER,
        eps,
        |event| async {
            match event {
                Event::Apply(eps) => reconcile(&eps, ctx.clone()).await,
                Event::Cleanup(eps) => cleanup(&eps, ctx.clone()).await,
            }
        },
    )
    .await
    .unwrap();

I tried to get deleting resources with the finalizer function.
However, I got the error logs below and cannot add the finalizer to Endpointslice resources.

2023-10-12T14:42:48.275224Z  WARN reconciling object{object.ref=EndpointSlice.v1.discovery.k8s.io/app-svc-local-cmffz.test object.reason=object updated}: sartd::kubernetes::context: reconcile failed: FinalizerError(AddFinalizer(Api(ErrorResponse { status: "Failure", message: "the server could not find the requested resource", reason: "NotFound", code: 404 })))

I'm not sure a way to watch resources with the event type, such as applying, updating, and deleting.

How can I watch and get events and resources?

Thank you!

Hey. The finalizer fn is to help abstract the management of Kubernetes finalizers, not to give precise watch events.
There are some docs on https://kube.rs/controllers/gc/#finalizers which talks about the secret_syncer example.

I think your error is passing an Api:all to finalizer, but you have a namespaced resource. The Api::all can only be used to view events across namespaces, not to patch namespaced resources (see #1030). Note how secret_syncer is creating an Api::namespaced for the namespace of the object.

I appreciate your help!

I fully misunderstood the usage of Api::all() and Api::namespaced().
And I could reconcile Endpointslices.

Thank you.
