This may be accidentally fixed by https://gerrit.wikimedia.org/r/c/mediawiki/extensions/VisualEditor/+/675582.

There are still errors in the last 24hrs but I am not sure if 675582 was deployed so maybe that's expected.

Logstash search to check once this is deployed: https://logstash.wikimedia.org/goto/fed16418131fdb4154f5f2904d2c8c53

This would appear to have completely stopped as of August 27th, which lines up nicely with the deployment.
