Hi there,

I believe this maybe a bug or at least an unchecked condition (post/page does not exist) throwing the above error. I have legit crawlers visiting that cause these errors.

Running 5.3.2. All plugins disabled (except for Health Check & Troubleshooting). Theme: Twenty.

How to re-produce : https://your.site.com/news2020/feed/atom/

It is key that the slug for the post/page does NOT (NO longer) exists.
