Kube-system snapshot-controller unable to retrieve pull secret

Hi, this error is going happening every few minutes in the syslog on the VM of a kubernetes cluster.

kubelet_pods.go:897] “Unable to retrieve pull secret, the image pull may not succeed.” pod=“kube-system/snapshot-controller-84f7b9d567-zfkr9” secret=“” err=“secret "my-registry-secret" not found”

The secret if of type: kubernetes.io/dockerconfigjson

The secret is for a pod in another namespace. We never intended it to be read in kube-system. Anyone have any idea why this is going on ?

Cluster information:

Kubernetes version: 1.25.4
Cloud being used: Azure VM
Installation method:
Host OS: Ubuntu 22.04
