Trying to convert ioredis code to node-redis (Typescript)

Getting started with Redis
1

Trying to convert the following code (ioredis):

 // Get JSON array of all currently active game IDs.
app.get('/api/activegames', async (req: Request, res: Response) => {

   console.log(req); //gets rid of typescript error.
  // Scan through all keys in the stream starting with "kaboom:moves".
  const stream = redis.scanStream({
    match: 'kaboom:moves:*'
  });

  const gameIds:any = [];

  stream.on('data', (keys) => {
    // Extract the gameId from the key and append to gameIds array.
    keys.forEach((key) => gameIds.push(key.split(':')[2]));
  });

  stream.on('end', () => {
    res.status(200).json({
      data: {
        gameIds,
        length: gameIds.length
      },
      status: 'success',
    })
  })
});

This is what I have so far, not working:

app.get('/api/activegames', async (req: Request, res: Response) => {

  const stream = client.scanIterator({
  TYPE: 'string', // `SCAN` only
  MATCH: 'kaboom:moves:*',
  COUNT: 100
  });

  const LIMIT = 3;

  const asyncIterable = {
    [Symbol.asyncIterator]() {
      let i = 0;
      return {
        next() {
          const done = i === LIMIT;
          const value = done ? undefined : i++;
          return Promise.resolve({ value, done });
        },
        return() {
          // This will be reached if the consumer called 'break' or 'return' early in the loop.
          return { done: true };
        }
      };
    }
  };

  (async () => {
    for await (const keys of stream) {
     gameIds.push(keys.split(':')[2]);
    }
  })();

 const gameIds:any = [];

 (async () => {
  for await (const keys of stream) {
   gameIds.push(keys.split(':')[2]);
  }
})().then(
  res.status(200).json({
  data: {
    gameIds,
    length: gameIds.length
  },
  status: 'success',
}));


});

app.get('/api/activegames', async (req: Request, res: Response) => {
  const gameIds: Array<string> = []
  for await (const key of client.scanIterator({ MATCH: 'kaboom:moves:*' })) {
    gameIds.push(key.split(':')[2]);
  }

  res.status(200).json({
    data: {
      gameIds,
      length: gameIds.length
    },
    status: 'success'
  });
});
