Ansible: Creating multiples paths with usernames defined in vars file - ansible

Question

How can I create multiple paths with usernames defined in vars file?
---
- hosts: hostname
gather_facts: false
vars_files:
- /home/ansible/usernames
tasks:
- name: Checking if home directory exists
with_items: "{{ username }}"
vars:
paths: &paths
- "/home/{{ username }}/"
- "/home/{{ username }}/data"
loop: "{{ paths }}"
become: yes
become_user: "{{ username }}"
stat:
path: "{{ paths }}"
register: play1
- name: Check paths from play1
debug:
var: play1
- name: Creating directories
loop: "{{ play1.results }}"
register: play2
become: yes
become_user: "{{ item.item }}"
file:
path: /home/{{ item.item }}/.ssh
state: directory
mode: '0700'
owner: "{{ item.item }}"
group: "system-group"
when: not item.stat.exists and not item.stat.pw_name == '"{{ item }}"'
- name: Display Creating directories
debug:
var: play2
Extract from input file.
username:
- user1
- user2
This is the error I'm getting:
ERROR: failed: [server] (item=/home/[u'user1', u'user2']/) => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"}, "ansible_loop_var": "item", "changed": false, "item": "/home/[u'user1', u'user2']/", "module_stderr": "Shared connection to server closed.\r\n", "module_stdout": "sudo: unknown user: [uuser1,\r\nsudo: unable to initialize policy plugin\r\n", "msg": "MODULE FAILURE\nSee stdout/stderr for the exact error", "rc": 1}
