FIX ERROR – Ansible AWS SSM: AnsibleError: An unhandled exception occurred while templating

When trying to get a value from AWS SSM, Ansible Playbook using Python3 as an interpreter generates the following error:

fatal: [localhost-py3]: FAILED! => {"changed": false, "msg": "AnsibleError: An unhandled exception occurred while templating '{{ lookup('aws_ssm', 'server_listeners', decrypt=false, region=’eu-west-1′) }}'. Error was a <class 'ansible.errors.AnsibleError'>, original message: An unhandled exception occurred while running the lookup plugin 'aws_ssm'. Error was a <class 'ansible.errors.AnsibleError'>, original message: botocore and boto3 are required for aws_ssm lookup."}

The Ansible documentation says that dependencies are needed for PIP:

• boto3
• botocore

But the error was still present until the "ansible" module was added to the PIP dependency

Solution:

---
- name: Ensure boto3, botocore and ansible modules are installed
  pip:
    name: 
      - boto3
      - botocore
      - ansible
    executable: /usr/bin/pip3
