Ansible realpath not working?

gistfile1.txt

On the machine:

root@proxmox01:/# ls -al /root/.ssh/authorized_keys 
lrwxrwxrwx 1 root root 29 Sep 26 10:40 /root/.ssh/authorized_keys -> /etc/pve/priv/authorized_keys

In the playbook:
- debug: msg={{ '/root/.ssh/authorized_keys' | realpath }}

Output:
TASK [customers : debug] *******************************************************
ok: [proxmox01] => {
    "msg": "/root/.ssh/authorized_keys"
}
