WIndows specific task FAILED when run playbook for linux

I'm trying to install datadog-agent with datadog-puma integration on a completely new clean ubuntu 16.04 host!

Here's my playbook:

---
- name: Install Datadog Agent
  # hosts: all
  hosts: testing
  become: true
  user: ubuntu

  roles:
    - { role: Datadog.datadog, become: yes }
  vars:
    datadog_enabled: false
    datadog_integration:
      datadog-puma:
        action: install
        version: 1.2.0

Result:

. . .

Since I'm using macOS & host running ubuntu, there is no sense to install ansible.windows collection, as mentioned in docs! Am I doing something wrong?
