我正尝试使用统一帐户发送现货订单。绝对没有关于此错误消息的含义的信息，就我从ByBit v5 API文档中所知，我做的一切都是正确的。我已经确定签名格式正确。这是发送沿着请求：

RequestBuilder {
method: POST,
url: Url {
    scheme: "https",
    cannot_be_a_base: false,
    username: "",
    password: None,
    host: Some(
        Domain(
            "api.bybit.com",
        ),
    ),
    port: None,
    path: "/v5/order/create",
    query: None,
    fragment: None,
},
headers: {
    "content-type": "application/json",
    "x-bapi-api-key": xxxxxxxxxxxxxx,
    "x-bapi-timestamp": "1676755850417",
    "x-bapi-sign": xxxxxxxxxxxxxxxx,
    "x-bapi-recv-window": "5000",
},}

发送请求时附加的请求正文：

{"category":"spot","symbol":"ETHUSDT","side":"Sell","order_type":"Market","qty":"0.1"}

这是用于发送请求的Rust代码：

// Set up the HTTP client
    let client = reqwest::Client::new();
    let mut headers = HeaderMap::new();
    headers.insert("Content-Type", HeaderValue::from_static("application/json"));
    headers.insert("X-BAPI-API-KEY", HeaderValue::from_str(&api_key)?);
    headers.insert("X-BAPI-TIMESTAMP", HeaderValue::from_str(&timestamp)?);
    headers.insert("X-BAPI-SIGN", HeaderValue::from_str(&sign)?);
    headers.insert("X-BAPI-RECV-WINDOW", HeaderValue::from_static(recv_window));

    let body = serde_json::to_string(&order)?;

        // Submit the order
        let request = client
            .post("https://api.bybit.com/v5/order/create")
            .headers(headers.clone())
            .body(body.clone());

        let response = request.send().await?;

以下是收到的答复：
