I'm continuously encountering the following error in the logs and am unsure of its cause. Recently, I upgraded Umbraco from version 10 to 13, and since then, this error has persisted. However, it doesn't appear to affect any user interface features so far. Anyone you have any idea what might be causing this error and how to fix it? I am currently using Umbraco 13.3.2.
