No recent occurrences since the change for this task was deployed as part of the 1.46.0-wmf.10 train on January 8th on Wikipedias.

See https://logstash.wikimedia.org/goto/2e8b4366df13c9f6fab53ca1a27b1397

(The underlying issue that we sometimes are missing data, that is still happening and logged in logstash, but not as an unhandled exception but in the GrowthExperiments channel.)

Leaving open for now and moving to QA so that it can be confirmed again after the A/B test officially starts and we have a lot more data.

Michael moved this task from Incoming to QA on the Growth-Team (FY2025-26 Q3 Sprint 1) board.Jan 21 2026, 4:56 PM

Etonkovidova moved this task from QA to Test in Production on the Growth-Team (FY2025-26 Q3 Sprint 1) board.Jan 21 2026, 7:23 PM

The last timestamp for the error - Jan 7, 2026 @ 17:25:02.362 (https://logstash.wikimedia.org/goto/26401480160e75e228f79004155a4f83).

The error rate was low. I think the task can be closed for now; after the A/B test starts, any errors would be closely monitored.
