Can you test the plugin on clear server without other plugins? 
I tested on Oxide and Carbon and i don't have this problem, it's something with your server probably

Any luck with it?

The problem is soon found! I have some self-written plugins that are not available anywhere. I disabled it in the plugin Update Checker checking for updates of unknown plugins. Through the GUI command uctest, but the error still appears, in general it does not affect the server in any way. Thank you for responding to my request!
