Podman fails in non-root ext4 mount

I am running:
podman --root="$EXT4_MOUNT_DIRECTORY/.podman" run debian:bookworm
And after completing the pull I am getting this error:

Error: mounting storage for container 84fb779af80275c138d9f6c5773e5dce27110c97e3b76d3eb467257c2b59c980:

No idea of the problem.
