Ansible with no action detected in task - ansible

Question

I would like to check TLS/SSL certificate expiration date from Ansible.
After execute a valid YML (ansible-playbook TEST.yml) appears the following error:
ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path.
The error appears to have been in '/scripts/Ansible/TEST.yml': line 15, column 7, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
- name: check validity
^ here
This is the code:
- name: find cerfication files & expiration dates
hosts: 10.0.1.41
gather_facts: false
tasks:
- name: Find cert files under /etc/pki/tls/certs
find:
paths: /etc/pki/tls/certs
file_type: file
patterns: "*.crt"
recurse: yes
excludes: "localhost.crt"
register: find_result
- name: check validity
openssl_certificate_info:
path: "{{ item.path }}"
valid_at:
point_1: "+1w"
point_2: "+10w"
register: result
loop: "{{ find_result.files|flatten(levels=1) }}"
- debug: msg= "{{ result }}"
What's the exactly wrong?
My version:
[root#ansible Ansible]# ansible-playbook --version
ansible-playbook 2.6.20
config file = /etc/ansible/ansible.cfg
configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
ansible python module location = /usr/lib/python2.6/site-packages/ansible
executable location = /usr/bin/ansible-playbook
python version = 2.6.6 (r266:84292, Jun 20 2019, 14:14:55) [GCC 4.4.7 20120313 (Red Hat 4.4.7-23)]

You are on a really old version of Ansible, I would recommend you to upgrade since your version had an end of support long ago (November 6, 2019).
Now, the module you are trying to use didn't exist in the version 2.6, that's the reason for the error raised by Ansible.
In the version 2.6, the way to check a certificate was to use the openssl_certificate module.
Something like:
- name: check validity
openssl_certificate:
path: "{{ item.path }}"
provider: assertonly
valid_at: 20171221162800Z
register: result
loop: "{{ find_result.files }}"
