How to pass NodeSelector in the elasticsearch helm chart?

Elastic Orchestration Elastic Cloud on Kubernetes (ECK)

I am trying to install elasticsearch in Kubernetes and I want to deploy the elasticsearch pod inside a particular node.

I am passing below config in yaml file -

elasticsearch:
  enabled: true
  replicas: 1
  minimumMasterNodes: 1
  fullnameOverride: "elasticsearch"
  imagePullPolicy: "Always"
  esJavaOpts: "-Xmx1024m -Xms1024m"
  maxUnavailable: 0
  clusterHealthCheckParams: "wait_for_status=yellow&timeout=20s"
  resources:
    requests:
      cpu: "100m"
      memory: "256M"
    limits:
      cpu: "2000m"
      memory: "2048M"
  nodeSelector:
    name: "appnode"

I am getting the error below -

Please help to resolve the issue.
