Failed to integrate redis server with express node js app - node.js

Question

I am new to Node.js and I have been trying to create a small app integrated with KUE library for task queuing.
When I trying to run the app i.e. node app.js I get the following error:
{ ReplyError: ERR wrong number of arguments for 'set' command
at parseError (.......\node_modules\redis-parser\lib\parser.js:193:12)
at parseType (........\node_modules\redis-parser\lib\parser.js:303:14)
command: 'SET',
args: [ 'promotion:lock', 'H5BCCsomeRandomString==', 'PX', 2000, 'NX' ],
code: 'ERR' }
I did see this error at a lot of places but they all dont seem to be a solution for my problem.
Here is my app.js
var express = require('express');
var path = require('path');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var session = require('express-session');
var dotenv = require('dotenv');
dotenv.load();
var queue = require('./routes/queueJob');
var app = express();
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(session({
secret: 'secret',
resave: true,
saveUninitialized: true
}));
app.use(express.static(path.join(__dirname, 'public')));
app.use('/jobs', queue);
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: err
});
});
app.listen(3000);
And here is the routes/queuejob.js
var express = require('express');
var router = express.Router();
var kue = require('kue'),
jobs = kue.createQueue();
var env = {};
jobs.on('ready', () => {
console.info('Queue is ready!');
});
jobs.on('error', (err) => {
console.error('There was an error in the main queue!');
console.error(err);
console.error(err.stack);
});
router.get('/addnewjob', function(req, res) {
let callback = function() {
console.log('Callback has been triggered');
}
newJob('Request Job', callback);
res.end('Successfully added a new job');
});
function newJob(name, callback) {
name = name || 'Default_Name';
var job = jobs.create('new job', {
name: name
});
job
.on('complete', function() {
console.log('Job', job.id, 'with name', job.data.name, 'is done');
callback();
})
.on('failed', function() {
console.log('Job', job.id, 'with name', job.data.name, 'has failed');
callback();
})
job.save();
}
jobs.process('new job', function(job, done) {
setTimeout(function() {
console.log('Job Processing finished');
}, 5000);
done();
});
module.exports = router;
Since there isnt much in the error message I am not sure how to fix this issue. I would really appreciate some help on this.

A SET command in Redis has the following format:
SET key value [EX seconds] [PX milliseconds] [NX|XX]
In your error, it seems that you are trying to use the SET commands with many argurments that do not match the format:
command: 'SET',
args: [ 'promotion:lock', 'H5BCCsomeRandomString==', 'PX', 2000, 'NX' ],
