MediaWiki\Extension\CentralAuth\Special\SpecialCentralAutoLogin::execute: Bad token: {loginResult}exception.trace
Steady increase over the last couple of days: https://logstash.wikimedia.org/goto/cccee76a68927819ae85533c64548f9
It fixed itself:
We also had an increase in "Lost session" errors on the dashboard in the same time frame: https://grafana.wikimedia.org/d/000000004/authentication-metrics?from=now-7d
The blue markers here highlight that it started with the "group1 to 1.46.0-wmf.26" deployment and ended with the "group2 to 1.46.0-wmf.26" deployment.
This was probably caused by the same cache inconsistency issue as T424935, which also resolved itself once all wikis were on the same MediaWiki version.
