大佬们好，目前在尝试写一个api的客户端接口，调试了1天，出现此错误：

上面接口是get请求，本地可以直接访问；一直提示Error: error decoding response body: data did not match any variant of untagged enum HuobiResponse。

这部分代码如下：

#[derive(Deserialize, Serialize, Debug, Clone)]
pub struct HuobiErrorData {
    pub code: i64,
    pub msg: String,
}

#[derive(Deserialize, Serialize, Debug, Clone)]
#[serde(untagged)]
pub enum HuobiResponse<T> {
    Success(T),
    Error(HuobiErrorData),
}

impl<T: for<'a> Deserialize<'a>> HuobiResponse<T> {
    pub fn into_result(self) -> Result<T, Error> {
        match self {
            Self::Success(t) => Result::Ok(t),
            Self::Error(HuobiErrorData { code, msg }) => {
                Result::Err(Error::HuobiError { code, msg })
            }
        }
    }
}

不知道如何调试及错误的原因，希望大佬们给予指点。谢谢
