3.16: Does recover not receive CORS error messages?

[AshinZhou]

In the code listing, the CORS errors printed in section 3.16 are not the same as those printed in section 3.17.
I checked the GitHub documentation of warp and found that there are relevant issues.

`#[tokio::main]
async fn main() {
let cors = warp::cors()
.allow_any_origin()
.allow_header("content-type")
.allow_methods(&[Method::PUT, Method::DELETE, Method::GET, Method::POST]);

let get_items = warp::get()
    .and(warp::path("questions"))
    .and(warp::path::end())
    .and_then(get_questions)

// this
.recover(return_error);

let routes = get_items.with(cors);

warp::serve(routes)
    .run(([127, 0, 0, 1], 3030))
    .await;

}`
