WARN Item with ID={97ADE186-643D-46A9-BAC5-C88077260694} cannot be deleted because it is not found

Question

On our CD server i'm seeing a lot of warnings (see below), not quite sure where this is getting invoked from or whats triggering this even though the analytics and tracking is disabled.

Noticed Sitecore.ContentSearch.SolrProvider.Agents.IndexingStateSwitcher job starts frequently but not entirely sure if its caused by this. ( There's no other error or exception thrown)

Sitecore Verson 9.3

Answer 1

Just assuming that you might be using Glass Mapper.. if so, you are probably running into an issue in Glass for Sitecore 9..2+ as described here: https://github.com/mikeedwards83/Glass.Mapper/issues/402

Although the logs are probably annoying, you can ignore them as they are perfectly safe. Apparently Sitecore changed added some logging to the item delete method causing all those logs - but there is nothing wrong with your setup.

If you want to get rid of the messages, you could filter them - check this Q/A for ideas on that: Filter standard Sitecore log messages into separate logs
