Describe the issue
A valid playbook with an empty tasks section will cause a python exception and subsequently an abnormal exit for Checkov. An example for this is a simple playbook that calls a role. This is a valid ansible playbook, works in ansible, and is seen as valid by ansible-lint.

Examples

A Playbook of:

---
- name: Using a Role
  hosts: all
  roles:
    - role: somerolename
  tasks:

will cause a python exception: (trimmed)
