### Bug description

Previously, Jupyterhub on EKS 1.26. Now we upgraded the EKS version to 1.27. All the components are up and running (pods, services). I can see the sign in page. But once I login, the user pod and PVC are in pending state and not able to launch the jupyter server.

Below is the error from scheduler pod

```auto
W0111 05:33:10.904864 1 reflector.go:324] [k8s.io/client-go/informers/factory.go:134](http://k8s.io/client-go/informers/factory.go:134): failed to list *v1beta1.CSIStorageCapacity: the server could not find the requested resource
E0111 05:33:10.904941 1 reflector.go:138] [k8s.io/client-go/informers/factory.go:134](http://k8s.io/client-go/informers/factory.go:134): Failed to watch *v1beta1.CSIStorageCapacity: failed to list *v1beta1.CSIStorageCapacity: the server could not find the requested resource

```

So we upgraded kube-scheduler to 1.26 version. Now scheduler pod itself is erroring out with this error

```auto
1 run.go:74] "command failed" err="couldn't create resource lock: endpoints lock is removed, migrate to 
endpointsleases"

```

### How to reproduce

Deploy JupyterHub helm chart 1.1.3 (App version 2.3.1) on eks 1.26 version. Upgrade eks to 1.27 version

#### Expected behaviour

All pods should be up running

#### Actual behaviour

Scheduler pod doesn’t come up
