I am getting this error

no matches for kind "PrometheusRule" in version "monitoring.coreos.com/v1

I have deployed kps using flux kustomize.
I am trying to create alert rules . I have created a file name with node-rules.yaml having different rules , but when I run I get this error.

  Please add ignored mountpoints in node_exporter parameters like

  "--collector.filesystem.ignored-mount-points=^/(sys|proc|dev|run)($|/)".

  Same rule using "node_filesystem_free_bytes" will fire when disk fills for non-root users.

I am looking forward to get suggestions regarding this.

We need to add alerts additionalPrometheusRule: in kps. This is how I fixed the issue.
