TypeError: Cannot read property 'replace' of null

See original GitHub issue

I’m getting the following error a lot when trying to access pages in the web UI:

Could you attach an image of a console shot

It just has the same stacktrace I posted above. No other logs.

how you’re running arena (container vs full app)

We’re not running inside a container. Just mounting it with express:

const http = require('http');
const express = require('express');
const arena = require('bull-arena');

const arenaConfig = {
  queues: ...
};
const app = express().use(arena(arenaConfig, {disableListen: true}));

http
    .createServer(app)
    .listen(9000);

We’re also seeing some weird jobs in Bull. It may be that Arena doesn’t like that. I can provide more detail once I can figure out what’s going on in Bull.

@skeggse Are you asking me if I remember something from 7m ago? 🤣

IIRC I looked at the code then and there was something fishy going on related to this issue. You’ll see I posted Jan 30th, 2020, and #148 was posted Feb 1, 2019. The issue is the same as #148 certainly, but might have been caused by this issue. I don’t know.

But, when we’re talking a turnaround time of nearly two years to triage bugs, your guess is as good as mine.
