How to convert web::types::Payload to AsyncRead

[nanakura]

I made some attempts

use futures::TryStreamExt;
use ntex::web;

#[web::get("/")]
async fn hello(body: web::types::Payload) -> impl web::Responder {
    let reader = body.into_async_read();
    web::HttpResponse::Ok().finish()
}

#[ntex::main]
async fn main() -> std::io::Result<()> {
    web::HttpServer::new(|| {
        web::App::new()
            .service(hello)
    })
        .bind(("127.0.0.1", 8080))?
        .run()
        .await
}

I get the following error

error[E0271]: type mismatch resolving `<Payload as Stream>::Item == Result<Bytes, Error>`
    --> src\main.rs:6:23

I tried implementing it manually
