-When the request handler is invoked, it expects a request attribute to be defined that contains a reference to the handler. The handler must be a string, a `Closure` or an object implementing `MiddlewareInterface` or `RequestHandlerInterface`. If it's a string, a `ContainerInterface` will be used to resolve it and get the `MiddlewareInterface` or `RequestHandlerInterface` to use. If it's a `Closure`, will be converted automatically to `MiddlewareInterface` using the [`Middlewares\Utils\CallableHandler`](https://github.com/middlewares/utils#callablehandler)
