failed to list *v1.Namespace: the server could not find the requested resource

[riddhichheda03]

Hi,
We are trying to deploy reloader on openshift v4.16 and we are using namespaceselector to monitor specific namespaces. And we have given all the necessary access to the SA.
We are getting below error:
time="2025-03-06T14:19:39Z" level=info msg="Starting Controller to watch resource type: secrets"
W0306 14:19:39.762652 1 reflector.go:561] pkg/mod/k8s.io/[email protected]/tools/cache/reflector.go:243: failed to list *v1.Namespace: the server could not find the requested resource
E0306 14:19:39.762726 1 reflector.go:158] "Unhandled Error" err="pkg/mod/k8s.io/[email protected]/tools/cache/reflector.go:243: Failed to watch *v1.Namespace: failed to list *v1.Namespace: the server could not find the requested resource" logger="UnhandledError"

Could you please help us on this?

hi @riddhichheda03 is the cluster under load, how many namespaces do you have in the cluster? and which version of reloader is running

[riddhichheda03]

Without using namespaceselector it is able to monitor the secrets and config for my specified namespaces. But with namespaceselector it gives above error.

Can you share what namespace selector are you using? And are you able to see namespaces with that selector using kubectl get ns -l <selector>

[riddhichheda03]

yes, I am using namespaceselector as "managedby=test".
oc get ns -l managedby=test
NAME STATUS AGE
test-project1 Active 407d
test-project2 Active 226d

We have deployed reloader 1.3 using helm.
Also how can we monitor multiple namesapces ?
