Summary

Running ansible-lint against the playbook produces a fatal violation.

Looking at the source code of the module it seems the arguments mentioned in the violation are set to be required although they are hidden. We presume this is what's causing this issue.

Steps to reproduce

Create a playbook file with the contents below. Then run ansible-lint against the playbook file.

---
- name: NTP
  hosts: all
  gather_facts: false
  connection: local

- name: Play
  hosts: all
  tasks:
    - name: Set ntp
      juniper.device.command:
        commands:
          - set date ntp 1.2.3.4

Expected results

No violations to be produced by ansible-lint

Actual results

ansible-lint produces violations

user@machine JunOS % ansible-lint linttest.yml
WARNING  Listing 1 violation(s) that are fatal
args[module]: missing required arguments: _inventory_hostname, _module_name, _module_utils_path (warning)

With an up-to-date Ansible version (2.16.x) this now seems to be a fatal error during playbook execution:
