Jobs fail to start with: cannot set blockOwnerDeletion

[mauricio-usatai]

Hi, I am trying to run cronjobber in an Openshift v4.6 cluster; Kubernetes v1.19. I was able to deploy cronjobber via Helm chart provided in the repo but when I schedule a TZCronJob, I am getting this error when the job starts:

Warning FailedCreate 78s (x91 over 16m ) cronjobber Error creating job: jobs.batch "hello-1630089060" is forbidden: cannot set blockOwnerDeletion in this case because cannot find RESTMapping for APIVersion batch/v1beta1 Kind TZCronJob: no matches for kind "TZCronJob" in version "batch/v1beta1"

Here is the TZCronJob yaml I am using:

apiVersion: cronjobber.hidde.co/v1alpha1
kind: TZCronJob
metadata:
  name: hello
spec:
  schedule: "30 15 * * *"
  timezone: "America/Sao_Paulo"
  jobTemplate:

              image: busybox
              args:
                - /bin/sh
                - -c
                - date; echo "Hello, World!"
          restartPolicy: OnFailure
