I am attempting to install Ansible Automation Platform 2.5 using the bundled installation. It kept displaying the following error: ```auto "Ansible Automation Platform service nodes cannot exist on the same host. Please ensure each component node is on a separate VM as collocation of services such as controller and hub on the same host are not allowed." ``` I checked my inventory file, and I only included automation gateway, automation controller (hybrid), database and the necessary variables for redis, bundle and controller. (No automationhub included in the inventory) I do understand that for AAP 2.5, automation hub and controller must be on different nodes, but I am trying to install just the controller on this one node. Any help would be appreciated! ---
