K-S-M job stops when all (*) Label and annotations are allowed

[Sohamdg081992]

What happened: K-S-M job stops working when all Label and annotations are allowed when we upgraded ksm from 2.9.2 to 2.12.0.
This below setting is used.
--metric-labels-allowlist=asterix=[asterix]
--metric-annotations-allowlist=asterix=[asterix]

What you expected to happen: The job should continue working and labels and annotations should flow. They are working in ksm version 2.9.2 with same label and annotation settings.

How to reproduce it (as minimally and precisely as possible):

# An example: https://github.com/kubernetes/kube-state-metrics/issues/2223#issuecomment-1792850276
minikube start
...
go run main.go --custom-resource-state-only --custom-resource-state-config-file ksm-2223/custom-resource-config-file.yaml --kubeconfig ~/.kube/config

Anything else we need to know?:

Environment:

• kube-state-metrics version: 2.12.0
• Kubernetes version (use kubectl version): 1.27.9
• Cloud provider or hardware configuration: Azure
• Other info:
