Were other users accessing the app at the same time, and editing content?

The same kind of issue: #15743.

Does this reproduce you on every index rebuild?

Could be two requests or threads saving the site settings.

@yqzhen1990 can you try with the latest main branch? We fixed a concurrency issue related to site settings that could explain it.

If not that, then maybe a background task that is updating the index is happening while the Rebuild is invoked from the UI, and that would be something to handle. To debug that we should add some logging to display when either is invoked/done and see if this is what is happening.

@sebastienros ok, I'll try with the latest main branch this weekend.
