This week's 1.43.0-wmf.9 version of MediaWiki is blocked[0].

We can't proceed until the following issue is resolved:

* T367334 - EntitySchema conditional namespace registration errors (NS_ENTITYSCHEMA_JSON, NamespaceRegistrationHandler::registerNamespace() TypeError) - https://phabricator.wikimedia.org/T367334

There's a patch which could probably use review at:

https://gerrit.wikimedia.org/r/c/mediawiki/extensions/EntitySchema/+/1042308

Once this issue is resolved, the train can proceed normally for the week.

Thank you for any help!
