Platform

NodeJS

What happened?

FlowProducer#getFlow() returns an array of undefined children when descendant jobs passed to FlowProducer#add() have queueNames containing colon (:) characters.

How to reproduce.

import { FlowProducer } from 'bullmq';

const flow = new FlowProducer();

const { job } = await flow.add({
  name: 'parent',
  queueName: 'parent',
  children: [{ name: 'child', queueName: 'parent:child' }]
});

const { children } = await flow.getFlow({
  id: job.id,
  queueName: 'parent'
});

console.log(children); // → [undefined]

It's probably this line:

const [prefix, queueName, id] = key.split(':');

...that's causing the problem.

Splitting/joining by : happens in a lot of places so it'd be nice to issue a warning if the user happens to choose a queue name or other identifier that contains a colon and might end up in those places to beware of the consequences.

Somewhat similar/related: #1334
