Description

Error

Logstash record

channel: Flow
level: ERROR
message:

Revision not found in revisionCache: {alpha}

Impact

Logstash query - a single request, generating 26 errors (lots of missing Flow revisions?). Happened on Special:Watchlist so presumably the impact is missing watchlist rows.

The message is in the flow extension at:

Can also happen for checkusers, but that code throws at:

This is not a production error but a diagnostic message logged to the Flow channel. Out of scope for train triage and general org-wide production error monitoring. This is not a statement about whether the error is important to the maintainers of the code.
