Here is a simple Ansible playbook:- name: this command prints FAILED when it fails  command: /usr/bin/example-command -x -y -z  register: command_result  failed_when: 'FAILED' in command_result.stderrNow, I know variable command_result has a method called stderr but how can I get a list of all methods?
Where can I find all the methods that I can call on an Ansible variable
