Misleading warning "is not valid under any of the given schemas" when linting tasks

[boutetnico]

Summary

I have a task file that is imported by a top-level playbook.
Ansible-lint reports a warning when checking the following file whereas I believe it is mistaken because the task works as expected. I suspect the environment key to cause the warning.

Issue Type

• Bug Report

OS / ENVIRONMENT

ansible-lint 6.10.2 using ansible 2.14.1

• ansible installation method: pip
• ansible-lint installation method: pip
• OS: macOS 12.6.1

STEPS TO REPRODUCE

Create the following test.yml file inside a tasks folder.

---
- name: Run npm run prod
  ansible.builtin.command: npm run prod
  environment:
    DISABLE_V8_COMPILE_CACHE: 1
  changed_when: false

Run ansible-lint:

ansible-lint tasks/test.yml

Desired Behavior

No warning is issued.

Actual Behavior

A warning is issued.

I am running ansible-lint v6.18.0 and have exactly the same bug. So not solved:

  register:     command_result
  failed_when:  command_result.rc > 2
  changed_when: command_result.stdout != ''

Desired Behavior

No warning is issued.

Actual Behavior

A warning is issued.
