I was trying to use a stream way to transfer a large file, but got error anyway. the log is above

pub struct S3Response<T> {
    /// Operation output
    pub output: T,

    /// Response headers, overrides the headers in `output`.
    pub headers: HeaderMap<HeaderValue>,

    /// Response extensions.
    ///
    /// It is used to pass custom data between middlewares.
    pub extensions: Extensions,
}
