Why is Ansible showing the error "ERROR! No action detected in task"?

Question

Ansible shows an error:

ERROR! no actions were found in the task. This often indicates the name of the module with an error or the wrong path to the module.

What's wrong?

---

Exact transcript:

ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path.

The error appears to have been in 'playbook.yml': line 10, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

---
- name: My task name
  ^ here

Reason number 1

You are using an older version of Ansible that did not have the module you are trying to run.

How to check it?

• Open the list of modules module documentation and find the documentation page for your module.

• Read the title at the top of the page - it usually shows the version of Ansible in which the module was introduced. For instance:

  New in version 2.2.

• , Ansible . Run:

  ansible-playbook --version
  

  . - :

  ansible-playbook 2.4.1.0
