<p>Ever since I upgraded my EKS cluster to <code>v1.21</code>, I get the following error when triggering Cronjobs manually:</p>
<pre><code>➜  ~ kubectl create job --from=cronjob/elt-dim-customer-new test-1 -n dwh-dev
error: from must be an existing cronjob: no kind &quot;CronJob&quot; is registered for version &quot;batch/v1&quot; in scheme &quot;k8s.io/kubectl/pkg/scheme/scheme.go:28&quot;

➜  ~ kubectl version

</code></pre>
<p>This is the Cronjob structure (you can see the <code>apiVersion</code>):</p>
<pre><code>apiVersion: batch/v1
kind: CronJob 
metadata:
  name: elt-dim-customer-new
spec:
  schedule: {{ .Values.cron }}
  successfulJobsHistoryLimit: 1
  failedJobsHistoryLimit: 1
  jobTemplate:

</code></pre>
<p>Couldn't find what has changed in EKS 1.21. Will appreciate your assistance!</p>

<p>Please upgrade your kubectl to 1.21 as well.</p>
