fix: socket.io has an unhandled 'error' event

[clempat]

Security alert triggered on our project highlighted the following issue.

The latest possible version of socket.io that can be installed is 4.4.1. The earliest fixed version is 4.6.2.

Impact

A specially crafted Socket.IO packet can trigger an uncaught exception on the Socket.IO server, thus killing the Node.js process.

node:events:502
    throw err; // Unhandled 'error' event
    ^
