pod stuck at pending with custom scheduler

i have created a custom scheduler, which has been in running state.

however, when i create a new pod, assigning it to the custom scheduler, through .spec.schedulerName. the pod has been stuck in pending state.

here are the sample configuration

scheduler.yml

apiVersion: v1
kind: Pod
metadata:
  creationTimestamp: null
  labels:
    component: kube-scheduler
    tier: control-plane
  name: my-scheduler
  namespace: kube-system
spec:
  containers:
  - command:
    - kube-scheduler
    - --authentication-kubeconfig=/etc/kubernetes/scheduler.conf
    - --authorization-kubeconfig=/etc/kubernetes/scheduler.conf
    - --bind-address=127.0.0.1
    - --kubeconfig=/etc/kubernetes/scheduler.conf
    - --leader-elect=true
    - --port=10351
    - --scheduler-nam=my-scheduler
    - --secure-port=10359
    image: k8s.gcr.io/kube-scheduler:v1.16.0
    imagePullPolicy: IfNotPresent

pod.yml

apiVersion: v1
kind: Pod
metadata:
  name: nginx
spec:
  schedulerName: my-scheduler
  containers:
  -  image: nginx
     name: nginx

turns out the issue was with the --leader-elect. seems like the scheduler is not able to move forward with the --leader-elect set to true.
