variables in group_vars and host_vars do not load when using inventory directory

[myprogra...@gmail.com]

A playbook I ran, returned this failure:

TASK [create-admin-user : Create the non-root user account] ********************
fatal: [415.791.30.131]: FAILED! => {"msg": "The task includes an option with an undefined variable.
The error was: 'admin_user' is undefined\n\nThe error appears to have been in '/Users/pnotes/Code/terraform/pj1/ansi/roles/create-admin-user/tasks/main.yml': line 2, column 3,
but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n---\n- name: Task 1\n  ^ here\n"}

Given this directory structure:

├── ansible.cfg
├── inventories
│   └── test
│       ├── group_vars
│       │   └── all.yml
│       ├── host_vars
│       │   └── all.yml
│       └── hosts.ini
├── provision.yml
└── roles
    └── create-admin-user
        ├── handlers
        │   └── main.yml
        └── tasks
            └── main.yml

Note that is directory layout follows that given in the docs

And a role defined like this:  

- name: Create the non-root user account
  user:
    name: "{{ admin_user.name }}"
    password: "{{ admin_user.password | password_hash('sha512') }}"
    update_password: on_create
    group: sudo
    groups: sudo
    append: yes
    create_home: yes
    shell: /bin/bash

I expect the task, create-admin-user, defined above to pick variables defined in inventories/test/group_vars/all.yml  and inventories/test/host_vars/all.yml  but the error messages shows that these variables aren't.

This doesn't make sense to me given that group_vars && host_vars both follow this structure:

---
admin_user:
  name: somename
  password: "somepassword"
  ssh_public_key: '/Users/pnotes/.ssh/path_to_priKey'


ansible_become_pass: "somepasswd2"

I am bit confused as to what is happening - what am I missing?

host_vars/all.yml will not affect 'all hosts', just a host named
'all'. Still the group_vars/all.yml should work, my tests do show it
working, can you provide more info like the full error and -vvv
output?
