Current behaviour

Socket.io server crashes when the client sends invalid data.

Steps to reproduce (if the current behaviour is a bug)

Sending the data 442["some","data","that","breaks","stuff"] to the socket.io server.
Reproduces on most servers, sample server code:

const http = require('http')
const server = http.createServer()

server.listen(1337)

const io = require('socket.io').listen(server)

io.sockets.on('connection', (socket) => {})

Client-side (although this could come from any untrusted source)

var ws = new WebSocket('ws://localhost:1337/socket.io/?EIO=3&transport=websocket')
ws.send(`442["some","data","that","breaks","stuff"]`)

Expected behaviour

The server should not crash upon receiving this data.

Setup

• OS: Linux
• browser: Any, including headless clients
• socket.io version: 2.0.3
