Problem with @types/ws

[fkaempfer]

Screenshot

Expected Behaviour
My ts project does not compile when I use useServer from graphql-ws due to a typescript error in the definition file ws.d.ts.
It is fixed when I change line 2 to

import WebSocket, {WebSocketServer} from 'ws';

and delete line 8

Actual Behaviour
The project should compile

Debug Information
The error happens in node_modules/graphql-ws/dist/use/ws.d.ts during ts compilation. My project does not contain any errors

Further Information
My project is type: module.

I tried downgrading ws, @types/ws and graphql-ws but the error was never fixed.

My compilerOptions

 "compilerOptions": {
    "target": "ES2020",
    "module": "NodeNext",
    "lib": ["es2020", "DOM"],
    "moduleResolution": "nodenext",
    "allowJs": true,
    "outDir": "build",
    "rootDir": ".",
    "strict": true,
    "noImplicitAny": false,
    "esModuleInterop": true,
    "sourceMap": true,
    "allowUnreachableCode": true,
  },

Here is the diff that solved my problem:

Hey there, thanks for reporting. What version of ws are you using? Would you mind opening a PR?

Voilà. I'm using the latest ws ^8.18.3.
