ioRedis can't delete key in redis cluster

See original GitHub issue


ioRedis@4.9.0 (cluster mode) connect-redis@3.4.1 express-session@1.15.6 Redis Server Version: 5


ReplyErrorredis-parser.lib:parser in parseError errorCROSSSLOT Keys in request don’t hash to the same slot

the Reply errors contains :

{ command: { args: [ sess:6BSHHdpoqDVhpqWuOqrunZcqsUadtSEn, ], name: del } }

My code

const express = require('express');
const session = require('express-session');
const Redis = require('ioredis');

redisClient = new Redis.Cluster([{ 'host': host, 'port': port }]); 
const RedisStore = require('connect-redis')(session);

let sessionStore = new RedisStore({
    client: redisClient

    secret: 'mysecret',
    saveUninitialized: false,
    resave: false,
    store: sessionStore,
    cookie: {
        maxAge: 60 * 1000 // 1 minutes 


connect:redis DEL “Nu-53UpCkkG4XutUUFULWlWH_s-M2IU9” ioredis:redis write command[]: 0 -> del([ ‘sess:Nu-53UpCkkG4XutUUFULWlWH_s-M2IU9’, ‘’ ])

After seeing that I suppose that ioredis add a blank parameters and this is why it can’t delete my session key.

What is expected ?

I expect that my session key will be deleted in my redis cluster.

Thank in advance for your reply 😃
