Missing process handler in server-worker setup

Created by: omairvaiyani

We have a setup wherein some servers only add jobs to the queue, and some are set as workers to register and process the queue.

However, the servers receive the following error when adding to the queue:

Error: Missing process handler for job type AssignmentsIssueUpdate
    at Queue.processJob (/var/app/current/node_modules/bull/lib/queue.js:1006:7)
    at process._tickCallback (internal/process/next_tick.js:68:7)

The servers do not define a process handler, we only want the workers to process the queue. Is this an expected error?
