After updating core in MediaWiki docker, I get the following exception when trying to run an update:

docker-compose exec mediawiki php maintenance/update.php

Some of your configuration settings caused a warning:

• The Localtimezone setting must a valid timezone string or null. It must not be an empty string or false.

Please correct the issue before running update.php again.
If you know what you are doing, you can bypass this check
using --skip-config-validation.

I am wondering if it is intended that people must update their LocalSettings manually.

The error message was introduced in
