HTTP/1.1 sent to h2 connection with native-tls-alpn

[lilydjwg]

Code:

let _r = reqwest::get("https://www.google.com/").await.unwrap();

Cargo.toml:

reqwest = { version = "0.12.1", default-features = false, features = ["native-tls-alpn", "http2"] }

Result:

called `Result::unwrap()` on an `Err` value: reqwest::Error { kind: Request, url: Url { scheme: "https", cannot_be_a_base: false, username: "", password: None, host: Some(Domain("www.google.com")), port: None, path: "/", query: None, fragment: None }, source: Error { kind: SendRequest, source: Some(hyper::Error(Parse(Version))) } }

ALPN has negotiated to use h2 and then an HTTP/1.1 request is sent. The server terminates the connection by a GO_AWAY frame.

With http2_prior_knowledge it works fine.

Oops, it's fixed by #2165.
