InvalidAction: DescribeLaunchConfigurations

[Sameer Gautam]

I'm getting an issue with Launch Configuration while using Ansible's ec2_lc module. Listed below are few more details:

Backtrace

The full traceback is:
Traceback (most recent call last):

    }
...

Ansible Play

- name: Create Launch Configuration
  ec2_lc:
    region: "{{ region }}"
    name: "ansible-launch-config"
    image_id: "{{ image_id }}"
    instance_type: "{{ instance_type }}"
    security_groups: "{{ security_groups }}"
    state: present

System Details

ansible --version
ansible 2.5.0

boto version: 
import boto; print(boto.__version__)
2.48.0

I'm however able to call the corresponding function aws autoscaling create-launch-configuration ... without any problem.
