<p>I get the following error when trying to use the YAML file from my GitRepo to deploy to kube cluster.
<a href="https://i.stack.imgur.com/mCOSR.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/mCOSR.jpg" alt="Console errors" /></a></p>
<p>Here is the content of my .yaml file:</p>
<pre><code>apiVersion: v1
kind: Service
metadata:
  name: ts-service
spec:
  type: NodePort
  selector:
    app: ts
  ports:
  - protocol: TCP
    port: 8080
    nodePort: 8080

---

apiVersion: apps/v1
kind: Deployment
metadata:
  name: ts-deployment
  labels:
    app: ts
spec:
  replicas: 2
  selector:
    matchLabels:
      app: ts
  template:
    metadata:
      labels:
        app: ts
    spec:
      containers:
      - name: ts
        image: $DOCKER_IMAGE_NAME:$BUILD_NUMBER
        ports:
        - containerPort: 8080
</code></pre>
<p>I've already tried changing the ports, the API version to apps/v1, etc.
What seems weird to me is that no matter which line goes foirst in the file, it always shows me the same issue.
What can be causing this?</p>

<p>According to @hardway-studio ’s answer #4648446, Jackson 2 API plugin version 2.11.1 breaks our deployment.
To be precise, this commit：
<a href="https://github.com/jenkinsci/jackson2-api-plugin/commit/cbbdf36843505efd5d2d7cd4769018e4cc09f450" rel="nofollow noreferrer">https://github.com/jenkinsci/jackson2-api-plugin/commit/cbbdf36843505efd5d2d7cd4769018e4cc09f450</a></p>
<p>But if we downgrade the plugin directly, it will cause failure to load many other plugin.</p>
<p>My ugly way is to fork the plugin source code from <a href="https://github.com/jenkinsci/jackson2-api-plugin" rel="nofollow noreferrer">GitHub</a>, revert this commit and compile it. (Maybe this operation would break some other plugins?)</p>
<p>Manually upload the artifact(jackson2-api.hpi) to Jenkins and finally everything is fine, hope this problem can be fixed as soon as possible.</p>
