Impact
- About 160 events per 24 hours?
- Doesn't seem to affect user experience directly, but an unneeded module is being loaded (i.e. termbox)
Notes
- Errors happen when opening a Lexeme page, and on mobile version of the page only
- Example Logstash document: https://logstash.wikimedia.org/app/kibana#/doc/logstash-*/logstash-2020.10.07/clienterror/?id=AXUDJ5Yv1pGl6xFMAuJ-
- Very similar to the error we saw in T263982, that was created by T261488 and fixed by T264066.
- What this probably needs is to make sure that the new termbox is only loaded for items and properties. Alternatively, this task could be used to rethink this process more fundamentally and allow for implementing it in a clean way that supports both loading it for different entity types and both on mobile or desktop, all configurable.
- The refactor ("rethinking this process" the above point mentions) will be done if it turns out to be a simpler task than implementing a "quick fix". Otherwise the refactoring will be made a separate task to be triaged accordingly.
Acceptance Criteria
- Mobile page of Lexeme is rendered as expected
- There are no Error: invalid entity serialization errors reported in the client
