Problem with redis-adapter

[Natashkinsasha]

Hi. I faced with error. Try use nestjs, socket.io, redis-adapter, admin-ui.

     "socket.io": "4.4.1"
    "@nestjs/platform-socket.io": "^8.2.6",
    "@nestjs/websockets": "^8.2.6",
    "@socket.io/admin-ui": "^0.2.0",
    "@socket.io/redis-adapter": "^7.1.0",

export class RedisIoAdapter extends IoAdapter {
  constructor(
    private readonly redisClient: RedisClientType,
    private readonly appOrHttpServer: INestApplicationContext,
  ) {
    super(appOrHttpServer);
  }

  public createIOServer(port: number, options?: ServerOptions) {
    const pubClient = this.redisClient.duplicate();
    const subClient = this.redisClient.duplicate();
    const server = super.createIOServer(port, options);
    instrument(server, {
      auth: false,
      store: new RedisStore(this.redisClient.duplicate()),
      serverId: `${os.hostname()}#${process.pid}`,
    });
    server.adapter(createAdapter(pubClient, subClient));
    return server;
  }
}

        return Promise.reject(new errors_1.ClientClosedError());

Hi! redis@4 now requires that users manually call redisClient.connect().

I've updated the guide here and added an example here.

Please reopen if needed!
