bug: Regression in syncing

[mjudeikis]

Describe the bug

Few weeks ago, sync agent was working with https://cloudnative-pg.io/ :

apiVersion: syncagent.kcp.io/v1alpha1
kind: PublishedResource
metadata:
  name: publish-cnpg-cluster
spec:
  resource:
    kind: Cluster
    apiGroup: postgresql.cnpg.io
    version: v1
  naming:
    # This is the implicit default configuration.
    namespace: "$remoteClusterName"
    name: "$remoteName"
  related:
  - kind: Secret
    origin: kcp
    identifier: credentials
    reference:
      name:
        path: "spec.superuserSecret.name"

Now it gives error:

feels like a regression of some sort.
