Why doesn't reqwest take status and body from a server error?

[MordechaiHadad]

I have an axum server where if you post a file to it without a header attached, it will return 500 code with something like: "Header x is not specified"
so let's say this given request:

    let request = client
        .post(request_url)
        // .header("file-type", "groups")
        .multipart(form).send().await.unwrap();

When commenting out this header() it will panic as expected from an unwrap() but instead of giving me the actual status code and error body the server sends I get this instead:

thread 'tokio-runtime-worker' panicked at 'called `Result::unwrap()` on an `Err` value: reqwest::Error { kind: Request, url: Url { scheme: "http", cannot_be_a_base: false, username: "", password: None, host: Some(Domain("localhost")), port: Some(3000), path: "/upload", query: None, fragment: None }, source: hyper::Error(BodyWrite, Os { code: 10053, kind: ConnectionAborted, message: "An established connection was aborted by the software in your host machine." }) }', src\main.rs:124:39

Only when I uncomment header() it will run as it should, which is the expected behavior.
