redis v4 list sorted in reverse order

I am trying to get a list in reverse score order.

I am using node redis v4.0.1 which no longer supports client.ZREVRANGEBYSCORE

If I try await client.zRangeByScoreWithScores(‘rankings’, ‘-inf’, ‘+inf’);
This produces a list in ascending order.
If I try await client.zRange(‘rankings’, ‘-inf’, ‘+inf’, {
BY: ‘SCORE’,
REV: true,
});
There is an empty list produced.

How do I get a list in reverse score order?

    I guess you’re looking for ZRANGEBYSCORE, not the ‘rev’ one.

    So ZRANGEBYSCORE -inf +inf

    Try doing the following:

    await client.zRange('rankings', '+inf', '-inf', { BY: 'SCORE', REV: true, });

    When I checked out the documentation, you should switch min and max if you set REV to true.

    node redis v4.0 and the above version we use as below.

    client.sendCommand(['ZREVRANGEBYSCORE', 'players', '+inf', '-inf', 'WITHSCORES', 'LIMIT', '0', '3']).then(res => {
    console.log(res);
})
