Cannot do job.update when job runs in separate process

Created by: Gappa88

Description

I have changed the queue processor from a normal process to a separate process and now I cannot update a job anymore. It throws the following error: (node:7068) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): TypeError: job.update is not a function

Minimal, Working Test code to reproduce the issue.

// master.js

const Bull = require('bull');
const queue = new Bull("html_pusher", { redis: { "port": port, "host": "ip", "db": 0, "showFriendlyErrorStack": true, "password": "pwd" } });

const proc = require('./child.js');
queue.process(1, proc);

// child.js
module.exports = proc;

async function proc(job, done) {
  console.log(`HI JOB ${job.id}`);
  console.log(job);
  job.data.foo = 'bar';
  await job.update(job.data);
  return done();
}

when I convert the processor call to a separate process the job.update throws the error

// master.js

const Bull = require('bull');
const queue = new Bull("html_pusher", { redis: { "port": port, "host": "ip", "db": 0, "showFriendlyErrorStack": true, "password": "pwd" } });

queue.process(__dirname + "/child.js");

Bull version

3.4.8

Additional information

This is the content of job when processor is within the master process:

This is the content of job when job runs in a separate process:

{ id: '6604006',
  name: '__default__',
  data:
   { 
.... my data ....
  },
opts: { attempts: 1, delay: 0, timestamp: 1555080466092 },
progress: [Function],
  delay: 0,
  timestamp: 1555080466092,
  attemptsMade: 0,
  stacktrace: [],
  returnvalue: null,
  finishedOn: null,
  processedOn: 1555080467236 }

It seems that when the job is in a separate process some properties are missing.
