Should this be backported? I'm seeing 118,057+ errors over the last 7 days and the volume is high enough that it just triggered an alert (https://grafana.wikimedia.org/d/000000566/overview?tab=alert&viewPanel=16&orgId=1)

@Jdlrobson @SimoneThisDot Since there seems to have been a fix made that is included in 1.40.0-wmf.21, I'm going to remove this as a train blocker. Let me know if you object. A backport of the fix to wmf.20 is still welcome.

Checked

• betalabs doesn't display the error

• only pilot wikis on logstash (last 24 hours) show the error. The wikis are in group 2, so will check when the deployment (or backporting) will be for that group.
