Typescript is wrongly inferring types and showing errors

[Foxvyle-tec]

Describe the bug

After defining types for the socket instance, the compiler is inferring the arguments wrongly in CLI lib

To Reproduce

Please fill the following code example:

Socket.IO server version: 4.8.1

Server

import { Server } from "socket.io";

const io = new Server(3000, {});

io.on("connection", (socket) => {
  console.log(`connect ${socket.id}`);

  socket.on("disconnect", () => {
    console.log(`disconnect ${socket.id}`);
  });
});

Socket.IO client version: 4.8.1

Client

import { io,Socket } from "socket.io-client";

interface CliToServ{
 frdRequest:(user:{userId:string}) =>void;
 } 

interface ServToCli{
 hello:() =>void; 
}

const socket:Socket<ServToCli, CliToServ>= io("ws://localhost:3000/", {}); 

socket.on("connect", () => {
  console.log(`connect ${socket.id}`);
});

socket.on("disconnect", () => {
  console.log("disconnect");
});

//this is where it falsely shows the err
try{
const res=await socket.emitWithAck("frdRequest", {userId:"1234"})
} catch{
//err handling here
} 

//it says I passed 2 arguments and it 
//expected 1
//To resolve this I had to pass a second
//unwanted prop to the interface ie

interface CliToServ{
 frdRequest:(user:{userId:string}, x:unknown) =>void;
 }

//with the above the err doesn't show /
//and still it doesn't infer that useless 
//prop

Expected behavior
With valid type definition it had not to make any warnings, and there was no need for me to add an unwanted prop

Platform:

• Device: [Dell Latitude]
• OS: [windows 10]

Additional context

That unwanted prop added it's also not inferred on emittion
