Are you sure the assignment to $server is correct as (new \Skinny\Network\Server())->startup() (which targets Skinny\Network\Server::startup()) seems to always return null.
This check looks for function or method calls that always return null and whose
return value is assigned to a variable.

The method
getObject()can return nothing but null, so it makes no sense to assign that value to a variable.The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes.
