hmset error

[Napas]

I'm trying to use hmset:

           redisConnection.hmset(personId, {
                tagId: req.params.tagId,
                personHash: req.params.personHash
            }, function(err, reply) {
                if (err) {
                    throw err;
                }

                assert(reply, 'OK');
            });

And got error:
/app/node_modules/redis-cluster/node_modules/redis/index.js:563
throw callback_err;
^

So what is correct way to use hmset function?

I think problem at "personId", try "personId.toString()" please

[Napas]

Same error. hset works with personId.

Very strange, can you please provide more code, how you init redis-cluster etc...

And what OS you are using?

[Napas]

var cluster = require('cluster');

if (cluster.isMaster) {
    // Count the machine's CPUs
    var cpuCount = require('os').cpus().length;

    // Create a worker for each CPU
    for (var i = 0; i < cpuCount; i += 1) {
        cluster.fork();
    }
} else {
    var express = require('express');
    var app = express();

    var sha1 = require('sha1');
    var redis = require('redis-cluster').clusterClient;
    var assert = require('assert');
    var crypto = require('crypto');

    new redis.clusterInstance('127.0.0.1:6379', function(err, redisConnection) {    
        if (err) {
            throw err;
        }

        app.get(
            '/test-url/:personHash/:tagId',
            function(req, res) {
                var personId = sha1(crypto.randomBytes(24).toString('hex'));

                ...

                redisConnection.hmset(personId, {
                    tagId: req.params.tagId,
                    personHash: req.params.personHash
                }, function(err, reply) {
                    if (err) {
                        throw err;
                    }

                    assert(reply, 'OK');
                });
    });

        app.listen(3000);
        console.log('Application running!');
    });
}
