UserFills subscription does not work

[yassinekachrad]

use std::str::FromStr;

use ethers::types::H160;
use hyperliquid_rust_sdk::{InfoClient, Message, Subscription};
use tokio::sync::mpsc::unbounded_channel;


#[tokio::main]
pub async fn main() {
    let (sender, mut receiver) = unbounded_channel::<Message>();
    let address = H160::from_str("0x023a3d058020fb76cca98f01b3c48c8938a22355").unwrap();
    let mut info = InfoClient::new(None, None).await.unwrap();
    let i = info.subscribe(Subscription::UserFills { user: address }, sender).await.unwrap();

    println!("subscription idx: {}", i);

    loop {
        match receiver.recv().await {
            Some(msg) => {
                println!("{:?}", msg)
            },
            None => break,
        }
    }
}

Above sample code simply blocks in the loop, and does not receive any userFill event.

Please let me know if am I doing something wrong, or if it works on your machine.
