I'm trying to create a very simple reverse-proxy but I'm unable to send body to the second server, why?

[frederikhors]

I'm using the below code (from here) to create a simple reverse-proxy for my application.

It works except when it must pass the body to the second server.

The second server gets no body (payload) from this code, why?

use actix_web::{
    error::{self},
    web, Error, HttpRequest, HttpResponse,
};

use crate::server::AppState;

pub async fn identity_server_proxy(
    req: HttpRequest,
    payload: web::Payload,
    app_state: web::Data<AppState>,
) -> Result<HttpResponse, Error> {
    let forwarded_req = app_state
        .awc_client
        .request_from(
            format!(
                "{scheme}://{host}{path}{query}",
                scheme = "http",
                host = "localhost:3322",
                path = req.uri().path(),
                query = req.uri().query().unwrap_or(""),
            ),
            req.head(),
        )
        .no_decompress();

    let res = forwarded_req
        .send_stream(payload)
        .await
        .map_err(error::ErrorInternalServerError)?;

    let mut client_resp = HttpResponse::build(res.status());

    Ok(client_resp.streaming(res))
}

with awc_client: awc::Client::default() in AppState.
