在锁定钥匙redis-lock nodejs方面得到例外

Question

试图锁定哈希键时，请以下例外：

我正在引用以下文档：

https://redis.io/topics/distlock

https://github.com/mike-marcacci/node-redlock

var redis = require('redis');
var Redlock = require('redlock');
var redisClient = redis.createClient(settings.redisport, settings.redishost);
var redlock = new Redlock(
// you should have one client for each independent redis node
// or cluster
[redisClient],
{
    // the expected clock drift; for more details
    // see http://redis.io/topics/distlock
    driftFactor: 0.01, // time in ms
    // the max number of times Redlock will attempt
    // to lock a resource before erroring
    retryCount: 10,
    // the time in ms between attempts
    retryDelay: 200, // time in ms
    // the max time in ms randomly added to retries
    // to improve performance under high contention
    // see https://www.awsarchitectureblog.com/2015/03/backoff.html
    retryJitter: 200 // time in ms
 }
);
redlock.lock([Key], settings.lockttl).then(function (lock) {
    return lock.unlock();
}).catch(function (err) {
    return lock.unlock();
});

请建议我的代码中有什么问题。

没关系，这是我的错误。我错过了前缀'锁：'到键。

如果有人努力解决问题，则可以将其引用，顺便说一句，在文档中，尚未提及有关prefix '锁的方式：'键。
