Websocket connection closed when using fullstack

[niclashoyer]

Problem

I tried to use the new websocket feature from server_fn 0.8. I tried to roughly replicate the example from the release notes and I came up with this:

https://github.com/niclashoyer/dioxus-ws/blob/main/src/main.rs

Using dx serve it seems that the ws connection is proxied through, but I get the following error and the ws connection is closed:

Steps To Reproduce

git clone https://github.com/niclashoyer/dioxus-ws.git
cd dixous-ws
cargo install --git https://github.com/DioxusLabs/dioxus.git --rev cb651a8 --root . dioxus-cli
bin/dx serve

Expected behavior

Websocket connection is correctly handled by server function / axum.

Environment:

• Dioxus version: main, cb651a8
• Rust version: 1.86.0
• OS info: Fedora Linux 41
• App platform: web fullstack

@ealmloff do you have any idea why the connection just failed? Am I missing something from the leptos example?

[ealmloff]

Your code looks correct. I think this is a bug in the server function integration. It doesn't look like it is related to the CLI proxy. I can reproduce the issue when running the server directly

Thank you! Works as expected 🥇
