Cannot read property 'zrangebyscore' of null

I have 2 different job processors for the job

file1

var queue = kue.createQueue()
queue.process('myjob', function() {
    // first processor for "myjob"
})

file2

var queue = kue.createQueue()
queue.process('myjob', function() {
    // second processor for "myjob"
})

When i run their together, it throws the error:

C:\Projects\avito-parser\node_modules\kue\lib\kue.js:185
client.zrangebyscore(client.getKey('jobs:delayed'), 0, Date.now(), 'LIMIT', 0, limit, function( err, ids ) {
                          ^

Is it possible to use Kue in this way? PS looks like the issue happened only when i shutdown the queue and then create it again.

I've re-designed my app and issue disappeared.
