ec2_group failed to template

[Edgardo Vega]

I am having a strange issue 

I have a role that looks like the following

# roles/ec2_sg/tasks/main

- name: Create Security Group

  ec2_group:

    profile: "{{ profile }}"

    name:  "{{ type }}"

    description: "ports required to communicate to {{ type }}"

    vpc_id: "{{ aws_vpc_id }}"

    region: "{{ aws_region }}"

    rules: "{{ sg_rules }}"

When I have the following playbook it fails with the following error

- hosts: localhost

  connection: local

  gather_facts: false

  vars_files:

    - group_vars/{{ env }}

  tags:

    - test

  roles:

    - role: ec2_sg

      type: "test"

      sg_rules:

        - proto: tcp

          from_port: 8081

          to_port: 8082

          cidr_ip: "{{ public_cidr }}"

TASK: [ec2_sg | Create Security Group] ****************************************

fatal: [localhost] => Failed to template {% if [{'to_port': 8082, 'from_port': 8081, 'cidr_ip': u'0.0.0.0/0', 'proto': 'tcp'}] %} True {% else %} False {% endif %}: template error while templating string: expected token ',', got 'string'

FATAL: all hosts have already failed -- aborting

but if I do it works. 

- hosts: localhost

  connection: local

  gather_facts: false

  vars_files:

    - group_vars/{{ env }}

  vars:

    type: "test"

    sg_rules:

        - proto: tcp

          from_port: 8081

          to_port: 8082

          cidr_ip: "{{ public_cidr }}"

  tags:

    - test

  roles:

    - role: ec2_sg

      type: "test"

It really makes no sense. Does anyone have any idea what is happening?

Appreciate the help in advance.

Cheers,

Edgardo
