The auto-discovery example can only be used in the default namespace, and other namespaces cannot get the target

[AbelHugh]

kubernetes version: 1.24.4 kube-prometheus version: 0.12.0 doc site: https://github.com/prometheus-operator/prometheus-operator/blob/main/Documentation/user-guides/getting-started.md

I use the sample yaml file to deploy, and the target can be obtained, but once the namespace is changed, the target cannot be obtained

example： example.zip

command: kubectl apply -n test -f example/
