Socket-io client does not upgrade to Websocket, it just works as polling about socketioxide HOT 3 CLOSED

Part of the code that accomplishes this:
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    tracing::subscriber::set_global_default(FmtSubscriber::default())?;

    let messages = state::MessageStore::default();
    let sockets = state::SocketDataStore::default();

    let (layer, io) = SocketIo::builder().with_state(messages).with_state(sockets).build_layer();
    
    io.ns("/", |socket: SocketRef, Data(auth): Data<types::AuthData>, store: State<state::SocketDataStore>| async move {

               fn emit_wrapper(event: String, socket: &SocketRef, id: String, data: impl serde::Serialize) {
                    let _result = socket
                    .within(id)
                    .emit(event, data).ok();
                }

                emit_wrapper("person:connected".to_string(), &socket, socket_data.clone().id.clone().to_string(),
                    types::PersonConnected {
                        user_id: socket_data.clone().user_id,
                        extension: socket_data.clone().extension.clone().unwrap_or("".to_string()),
                    }
                );
    });
        let app = axum::Router::new()
        .route("/", get(|| async { "Hello, World!" }))
        .route("/hello", get(handler))
        .with_state(io)
        .layer(
            ServiceBuilder::new()
                .layer(CorsLayer::permissive())
                .layer(layer),
        );

    info!("Starting server");

    axum::Server::bind(&"0.0.0.0:3010".parse().unwrap())
        .serve(app.into_make_service())
        .await?;

    Ok(())
