Intro

First, I don't know the answer to this yet, so I can't tell you. What I can do is show you how I'd find the answer.

I'll be using line numbers, which will change when you merge master back into your branch. The commit I'm working off of is the current git HEAD of your PR.

Beacon Error Spam Investigation

Summary

I can't find any reason for this in the code. But based on its movement from staging to production at roughly our deploy cycle cadence, I advise checking to see if there is any environment/config changes that are responsible.

Problem

At some point, staging and production each started encountering the same error:

1. Purpose

This gist is to verify the safety and effectiveness of the script for backfilling document checksums. The script can be found on this mothership PR.

2. Script Requirements

This "script" is meant to fill in checksums for any documents table row that should have a checksum, but doesn't. Documents "should have" a checksum if pending == false. But not all do.

Goal: Side-by-side comparison of the same jobs, but two different views

We're introducing a new UI that will be feature-flagged. In order to determine that the new UI doesn't depart from the old UI in the wrong ways (e.g. not showing documents, or leaving off steps) we need to compare the new and old UIs when presenting the same jobs We'll select the three most-used recurring jobs from the six most active customers for this purpose.

Proposal: Two teams with identical jobs in a non-production environment

In environment E, we have two teams, T1 and T2. T1 has the new-UI feature flag on, but T2 doesn't.
