Jenkins – Deploy a Yaml file to Kubernetes from Pipeline Error

  css, html, javascript, jenkins, kubernetes

I cannot resolve an issue that I was stuck with in my beginner tutorial. When I try to create just a deployment on Kubernetes from Jenkins, I got the error message. How can I solve this problem? Could anyone pls help me?

Error

Starting Kubernetes deployment
Loading configuration: /var/lib/jenkins/workspace/k8sdeploy/k8sdeploy.yml
ERROR: ERROR: Can't construct a java object for tag:yaml.org,2002:io.kubernetes.client.openapi.models.V1Deployment; exception=Class not found: io.kubernetes.client.openapi.models.V1Deployment

    apiVersion: apps/v1
    ^

My Pipeline

pipeline {
  agent any
  stages {
    stage('Clone App from Github') {
      steps {
         git credentialsId: 'github', url: 'https://github.com/eneslanpir/k8sdeploy'
      }
    }
    stage("Wait For 5 Seconds"){
      steps {
        sleep 5
      }
    }
    stage("Kubernetes Create Deployment"){
      steps{
        script {
           kubernetesDeploy(configs: "k8sdeploy.yml", kubeconfigId: "kubeconfig")
        }
      }
    }
  }
}

My Deployment yaml from Github (Tested – Working on Kuberentes)

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment-jenkins
spec:
  selector:
    matchLabels:
      app: nginx
  replicas: 1
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx-jenkins
        image: nginx:1.16.1
        ports:
        - containerPort: 80
