STEPS TO REPRODUCE
Use this playbook (user, password and baseuri should be set to Redfish API credentials and endpoint):
- hosts: localhost
gather_facts: false
vars:
baseuri: redfish_api_entrypoint
user: test
password: test
tasks:
- name: Get all information available in all categories
redfish_facts:
category: all
command: all
baseuri: "{{ baseuri }}"
user: "{{ user }}"
password: "{{ password }}"
EXPECTED RESULTS
Facts about Redfish service are gathered and stored for later use.
ACTUAL RESULTS
Task failed during execution.
