Ansible and FortiGate Initial Configuration

Hi there:

Can you please try the following and let me know if that works ?

https://docs.ansible.com/ansible/latest/collections/fortinet/fortios/fortios_system_admin_module.html#examples

Thank you,

Hope.

Actually, that's been the URL I've been working off of.  

Again, this is a brand new FortiGate.  No passwords have been set.  I'm sure I'm missing something or doing something wrong.  To give you an idea of what I'm trying:

HOSTS:

[fortigates]
fortigate_pr ansible_host=192.168.1.99 ansible_user="admin" ansible_password=""

[fortigates:vars]
ansible_network_os=fortinet.fortios.fortios

YAML:

---

- hosts: fortigates
connection: httpapi
collections:
- fortinet.fortios
vars:
vdom: "root"
ansible_httpapi_use_ssl: yes
ansible_httpapi_validate_certs: no
ansible_httpapi_port: 443
tasks:
- name: Configure Admin User.
fortios_system_admin:
vdom: "{{ vdom }}"
state: "present"
system_admin:
name: "admin"
password: "password123"

ERROR:
