Openssl EOF error

[ethanthoma]

I am using dream to call hyper to make requests to Turso over http. When I send get or post requests, I get this:

My router code looks like this:

 let () = 
    run ~port:3000
    @@ logger
    @@ router [
        get "/turso/get" (fun _ -> 
            let%lwt str = Turso.hrana_support in
            str |> Dream.html
        );
    ]
;; 

Where my Turso module looks like this:

let url =
    match Sys.getenv_opt "TURSO_URL" with
    | Some value -> value
    | None -> failwith "TURSO_URL environment variable must be set."
;;

let hrana_support =
    let request =
        Hyper.request ~method_:`GET @@ url ^ "/v2"
    in
    let%lwt response = Hyper.run request in
    if Dream_pure.Message.status response = `OK then
        Hyper.body response
    else
        let%lwt () = Dream_pure.Message.close (Dream_pure.Message.client_stream response) in
        Lwt.fail (Hyper.Response response)
;;

The versions of my environment are: Ocaml compiler: 5.1.1 openssl: 3.2.1 dune: 3.14

Let me know what more information is required. Thanks!

Hey @ethanthoma ! Did you manage to find a workaround for this? I'm using Cohttp for requests, and getting the same error every now and then.

@Ali-7CC Lol nope. I wrote my turso connections using golang and compiled to c and used dune to connect it. You can see here
