Fatal error: Uncaught MediaWiki\OAuthClient\Exception: JWT has incorrect format

I just saw this error while viewing the main page. It worked fine after refreshing.

I saw this at some point too. Some sort of oauth expiry? Could’ve been triggered by something happening on meta. Haven’t touched that code recently.
