ReplyError: ERR unknown command 'evalsha' (Node.js, bull)

Question

I'm trying to work abound with the bull package with Redis on windows, my server is up and running but when I try to access the job it gives me an error, my code so far.

const queue = require('bull');
const jobs = new queue('jobs')

jobs.process((job, done) => {

    try {
        console.log(job)

    } catch (error) {
        console.log(error)
    }
   })

app.post('/upload', (req, res) => {

    let dat = req.query;

    jobs.add(dat).then(() => {
        console.log('done')
    }).catch(e => console.log(e))

    res.send('job done')
})

here is the error:

{ name: 'evalsha',
  args:
   [ '0a9a51ee96320953ec7bde8e63f3f060b9dac00c',
     '6',
     'bull:jobs:wait',
     'bull:jobs:paused',
     'bull:jobs:meta-paused',
     'bull:jobs:id',
     'bull:jobs:delayed',
     'bull:jobs:priority',
     'bull:jobs:',
     '',
     '__default__',
     '{"data":"muny"}',
     '{"attempts":1,"delay":0,"timestamp":1568792004594}',
     '1568792004594',
     '0',
     '0',
     '0',
     'LPUSH',
     '4fc02f94-d198-4353-b1b3-8da40399a9c5' ] } }

any guesses why so? also it's throwing unhandled promise rejection even when I've done so, is this behavior just for windows?

Answer 1

As I can see, You are using redis 2.4.6 but according to the doc:

EVALSHA sha1 numkeys key [key ...] arg [arg ...]
Available since 2.6.0.

So, that's why this error is throwing.

Now, basically if you cannot find a redis binary for windows you can download 3.2.1 from here
