My problem is :
DevTools failed to load source map: Could not load content for chrome-extension://flijfnhifgdcbhglkneplegafminjnhn/content/socket.io.js.map: System error: net::ERR_BLOCKED_BY_CLIENT
const express = require("express");
const path = require("path");
const http = require("http");
const app = express();
const server = http.createServer(app);
const socketIO = require("socket.io");
const io = socketIO(server)
const PORT = process.env.PORT || 3000;
io.on("connection",(socket)=>{
console.log("connection is completed with web socket");
console.log("socket is " + socket);
})
app.use(express.static(path.join(__dirname, 'src')))
server.listen(PORT,()=>{
console.log(`server is started at port on ${PORT}!`);
})
