Expected to see at least one deleted item in the feed

Rule type

Validation warning

Rule hint

Ensure that deleted items are included and flagged with "state": "deleted", and note that data must not be included for deleted items.

4.6 specifies how deleted items must be handled. There are no deleted items included in the feed at present, which usually indicates this has not been implemented. It's vital to ensure that events don't disappear from the API if they are deleted from the source system, as if this happens they will live on forever in the downstream apps and services that consume the feed, which will have cached the previously published version indefinitely.
