CephFilesystem: .spec.dataPools[0].name: field not declared in schema

[tadrian88]

Describe the bug

When deploying a rook-ceph filesystem through a flux kustomization, I get the error below.

CephFilesystem/rook-ceph/myfs dry-run failed, error: failed to create typed patch object (rook-ceph/myfs; ceph.rook.io/v1, Kind=CephFilesystem): .spec.dataPools[0].name: field not declared in schema

If using the same manifests but deployed through kubectl apply -k, the resources are getting deployed.

Steps to reproduce

1. Install a rook cluster with the following commands:

$ git clone --single-branch --branch v1.9.2 https://github.com/rook/rook.git
cd rook/deploy/examples
kubectl create -f crds.yaml -f common.yaml -f operator.yaml
kubectl create -f cluster.yaml

2. Deploy a rook filesystem using the manifest from the link below:

Flux uses server-side apply, I guess this is a bug in the CEPH CRDs, does it work if you do kubectl apply --server-side --dry-run=server?
