TypeError: Cannot read properties of undefined (reading 'id') when using createAdapter() from @socket.io/cluster-adapter

[michioxd]

Hi, I'm trying to set up Socket.IO with cluster support using PM2, following this docs.

Here's my code:

import { createAdapter } from "@socket.io/redis-adapter";
import { createAdapter as createClusterAdapter } from "@socket.io/cluster-adapter";
import { setupWorker } from "@socket.io/sticky";

const app = express();
export const server = http.createServer(app);
export const io = new Server(server, {
    transports: ['websocket', 'polling'],
    adapter: createAdapter(redisClient, redisSubClient)
});

io.adapter(createClusterAdapter()); // src/server.ts:76:4
setupWorker(io);

While I try to run my code, it showing this error

TypeError: Cannot read properties of undefined (reading 'id')
    at new ClusterAdapter (/home/michioxd/backend/node_modules/.pnpm/@[email protected][email protected]/node_modules/@socket.io/cluster-adapter/dist/index.js:61:34)

Command I used to run in PM2:

pm2 start index.js -i max

Thanks!
