Error One or more undefined variables unicode object has no attribute repo

Question

I have an Ansible role "db" with a simple task:

- name: Check repos
  apt_repository: repo="{{ item.repo }}" state={{ item.state }}
  with_items:
  - "{{ apt_repos }}"

In /defaults/mail.yml:

apt_repos:

   # Percona
 - { state: present, repo: 'deb http://repo.percona.com/apt wheezy main', keyserver: 'keyserver.ubuntu.com', key: '1C4CBDCDCD2EFD2A', needkey: True }
 - { state: present, repo: 'deb-src http://repo.percona.com/apt wheezy main', needkey: False }

When I try to run this ansible-playbook:

---
- hosts: test
  roles:
  - db

I see an error:

fatal: [10.10.10.10] => One or more undefined variables: 'unicode object' has no attribute 'repo'
FATAL: all hosts have already failed -- aborting

Hey change this in your role

with_items: apt_repos

By referencing it as - "{{ apt_repos }}" the extra - is turning it into a list of lists.
