SubPath support is broken or missing

[cornfeedhobo]

I have successfully installed the CSI driver, but when I make a pod there is a creation error:

Error: stat /data/kubelet/pods/71acd9f8-0469-4b44-8523-7276a646691f/volumes/kubernetes.io~csi/tls/mount: no such file or directory

I can see the directory only has vol_data.json:

{"attachmentID":"csi-d757e34a4db1de6adb6903587d8310b2f726fe24dc0c0d6cd97abad0017b95d0","driverName":"csi.cert-manager.io","nodeName":"k3s","specVolID":"tls","volumeHandle":"csi-510ce9dd2d1838b8d7126fa802b89a4b759abab419ee815edcc1fb98cb0d0c31","volumeLifecycleMode":"Ephemeral"}

I can list CertificateRequests and see that they have been made, approved, and report ready.

I've never seen a mount file referenced before and google doesn't turn up much.

Is it possible that using SubPath is causing this?

I've confirmed that removing subPath at least allows the pod to initialize.
