Node.js中console.log()输出WebSocket消息显示为<Buffer>而非文本的问题求助

大家好，我遇到了一个奇怪的问题：不管我怎么处理，Node.js里用console.log()输出WebSocket消息的时候，总是显示成<Buffer>格式，但这个问题只在VS Code的PowerShell集成终端里出现，在浏览器里消息显示是正常的。

客户端代码（client.html） #

<html>
<head>
<meta charset="UTF-8">
</head>
<script>
//calling the constructor which gives us the websocket object: ws
let ws = new WebSocket('ws://localhost:8000');
console.log(ws);

ws.onopen = (event) => ws.send("This is a message from client");
ws.onmessage = (message) => console.log(message.data.toString('utf8'))
</script>
<body>
<h1>This is a client page</h1>
</body>
</html>

服务端代码（server.js） #

const http = require("http");
const websocket = require("ws");

//creating a http server
const server = http.createServer((req, res) => {
res.end("I am connected");
});

const wss = new websocket.Server({ server });

wss.on("connection", (ws, req) => {
setTimeout(() => {
ws.send("This is a message from server, connection is established");
}, 3000);

ws.on("message", (msg) => {
console.log(msg.toString('utf-8'));
});
});

//making it listen to port 8000
server.listen(8000);

我试过直接访问WebSocket消息的[data]属性，也试过用.toString('utf-8')转换，但都没成功。

我的Node.js版本是v18.13.0。
