This deprecated member:
https://developer.roblox.com/api-reference/function/PathfindingService/ComputeRawPathAsync
Refers to the deprecated member:
https://developer.roblox.com/api-reference/function/PathfindingService/FindPathAsync
Which refers to the non-descriptive page:
https://developer.roblox.com/api-reference/function/PathfindingService/CreatePath
The CreatePath page as well as the other relevant members of PathfindingService need to be properly filled out with a description of what they do and a description of the parameters.
Moreover, the PathfindingService page (https://developer.roblox.com/api-reference/class/PathfindingService) does not list the specific members that are useful to pathfinding in the API listings, just the ones it inherits from its superclasses. I have to go to this page and scan over it to find out how to use pathfinding rather than having it available at a glance:
