Keda operator pod restarts because of objectScaler

[tomerle03]

Report

A scaledobject that causing the keda operator pod to reset

Expected Behavior

The scaledobject will not cause the keda operator pod to restart and affect the whole cluster

Actual Behavior

We are using Openshift in version 4.12 and keda in version 2.11. We have created a scaledobject that will sample Eck and will scale a DeploymentConfig in the cluster. Somehow this scaledobject caused the operator to restart a lot

Steps to Reproduce the Problem

1. Install keda in the operatorHub in version 2.11.2-322 2.deploy keda controller
2. Deploy scaledobject on deploymentConfig

Could you also provide the ScaledObject yaml?

could you paste here output of kubectl get scaledobject -oyaml -n NAMESPACE ?

And also more logs, as the attached are not correctly pasted, see this part: "resource": "/, Kind=", "

About the first question, do you need the status?

And secondly, the paste is correct I just checked. That's what weird.

[zroubalik]

Yes, full status.
