Ansible - No such file error when activating systemctl Podman user socket

I am running an Ansible playbook on a fresh Oracle Linux 8 system. It includes a step where it asks systemctl to activate a user Podman socket like so:

- name: Enable podman socket
  vars: 
    userid: ansible_facts.getent_passwd.{{ ansible_user_id }}[1]
  ansible.builtin.systemd: 
    name: podman.socket
    enabled: yes
    state: started
    scope: user
  environment:
    XDG_RUNTIME_DIR: "/run/user/{{ userid }}"

This Ansible playbook is being run as the user (not root) to enable and start the user-level Podman socket.

However, running the playbook gave me this error:

fatal: [127.0.0.1]: FAILED! => {"changed": false, "cmd": "/bin/systemctl --user", "msg": "Failed to connect to bus: No such file or directory", "rc": 1, "stderr": "Failed to connect to bus: No such file or directory\n", "stderr_lines": ["Failed to connect to bus: No such file or directory"], "stdout": "", "stdout_lines": []}

If, instead of using Ansible, I manually run the following systemctl command, then the user Podman socket activates successfully:

systemctl --user enable podman.socket

What am I missing in my playbook and how do I fix it? Thanks!
