Client getting disconnected when running socketio with bun

[23navi]

Describe the bug Client getting disconnected when running socketio with bun. The client is able to create the initial connection but after that, the client gets auto disconnect. I have tried the same with postman using socketio connection.

This happens only when I am running my server using bun, when using node runtime, I am not facing any issue.

Bun version: 1.0.0 Node version: v20.10.0

To Reproduce

Socket.IO server version: 4.8.1

Server

import express from "express"
import { Server as SocketServer } from "socket.io"
import cors from "cors"
import http from "http"
import dotenv from "dotenv"

dotenv.config()

const app = express()
const server = http.createServer(app)

app.use(cors())

const io = new SocketServer(server, {
    cors: {
        origin: "*",
        methods: ["GET", "POST"]
    }
})

io.on("connection", (socket) => {
    console.log(`User connected: ${socket.id}`)

    socket.on("process-video", (data) => {
        console.log(data)
    })

    socket.on("disconnect", (data) => {
        console.log("client got disconnected")
    })

})

server.listen(5001, () => {
    console.log("server is running on port 5001")
})

Socket.IO client version: 4.8.1

Client

import { io } from "socket.io-client";

const socket = io("ws://localhost:5001/", {});

socket.on("connect", () => {
  console.log(`connect ${socket.id}`);
});

socket.on("disconnect", () => {
  console.log("disconnect");
});
