Cannot perform %TypedArray%.prototype.set on a detached ArrayBuffer when using with Socket.io #705
Description
Hey
I'm trying to use uWebSockets with Socket.io,
but I keep getting this error, and I noticed that it only happens when I use Safari:
node:buffer:254
TypedArrayPrototypeSet(target, source, targetStart);
^
TypeError: Cannot perform %TypedArray%.prototype.set on a detached ArrayBuffer
at Buffer.set (<anonymous>)
at _copyActual (node:buffer:254:3)
at Function.concat (node:buffer:562:12)
at onEnd (/Users/.../node_modules/engine.io/build/transports-uws/polling.js:126:32)
at /Users/tahayk/.../node_modules/engine.io/build/transports-uws/polling.js:143:17
Node.js v17.0.1
Here is the example I used:
server.js:
const { App } = require("uWebSockets.js");
const { Server } = require("socket.io");
const app = new App();
const io = new Server({ cors: {
origin: "*",
methods: ["GET", "POST", "PUT"]
}});
io.attachApp(app);
io.on("connection", (socket) => {
// ...
});
app.listen(9000, (token) => {
if (!token) {
console.warn("port already in use");
}
});demo.html
