## TL;DR

After upgrading the Highlight JS SDK past 6.0.0, check whether you depended on console.error creating errors: if so, set reportConsoleErrors back to true in H.init. Treat any major-version SDK bump as a behavior-change review, not just a dependency update.

## Steps

1. After upgrading the Highlight JS SDK past 6.0.0, check whether you depended on console.error creating errors: if so, set reportConsoleErrors back to true in H.init. If you prefer the new default, make sure your dashboards and alerts read error logs too, or you will miss failures that used to page you. Treat any major-version SDK bump as a behavior-change review, not just a dependency update.

## When to use

You are seeing this: If you prefer the new default, make sure your dashboards and alerts read error logs too, or you will miss failures that used to page you. Use this skill when you run into "Highlight 6.0 turned off console.error as errors by default, check after upgrading".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

Versions mentioned in the source: past 6.0.0. If you are on something much newer or older, the details may have shifted.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
