Path header is prepended with scheme and authority when proxy option is set in HttpClient of Vertx

Question

I have a vertx app which sends the request to a proxy. It uses HttpClient with setproxyoptions. Then form a request using request options to set the actual host, port, method and path.

Vertx version: 4.4.0

public class MainVerticle extends AbstractVerticle {

    @Override
    public void start() throws InterruptedException {
        HttpClientOptions options = new HttpClientOptions().setProtocolVersion(HttpVersion.HTTP_2)
                .setForceSni(false)
                .setProxyOptions(new ProxyOptions().setHost("172.16.10.17").setPort(8080).setType(ProxyType.HTTP))
                .setHttp2ClearTextUpgrade(false);
        
        RequestOptions requestOptions = new RequestOptions()
                .setHost("127.0.0.1")
                .setPort(8080)
                .setMethod(HttpMethod.GET)
                .setURI("/nudr-dr/v1/subscription");
                
        HttpClient client = vertx.createHttpClient(options);
        client.request(requestOptions)
                .compose(request -> request.send().compose(response -> response.body()))
                .onSuccess(body -> System.out.println("HTTP/2 client received body: " + body.toString()))
                .onFailure(error -> System.out.println("HTTP/2 client error: " + error.getCause() + error.getStackTrace()));
    }
}

I expected to send the message something like below:

TCP/IP
    scr: 172.10.1.5:8080
    dest: 172.16.10.17:8080
HTTP2
    :method: GET
    :path: /nudr-dr/v1/subscription
    :scheme: http
    :authority: localhost

but the message was carrying the path prefixed with scheme and authority information :path: http://localhost/nudr-dr/v1/subscription

Note: This issue is not observed when the request is sent to the actual destination without setting the proxy option in HttpClient.

Why it is duplicating scheme and authority in path thought scheme and authority is mandatory and present in the request? Is this expected when it comes to proxy?

Path header is prepended with scheme and authority when proxy option is set in HttpClient of Vertx
