KubeJS Error Messages Upon Login

[AlisAquilae]

I just now updated to version 1.0.16 and restored my world file and options.txt file, after which I get the following error message when logging into the game:

Moreover, it refers to the server.txt in logs. Here's the file:
server.txt

Note that upon relogging, the error message disappears. I have not been able to replicate the issue since, but I felt it to be good practice to notify you anyways. Moreover, even after relogging, the server.txt file gives the same warning as provided in the file above, leading me to believe there is still some issue. I could not find what Item the error message was referring to, but you will probably know that better than me.

I did not fiddle with configs, did not add or delete mods, or anything else which I could imagine would break things.

Of course, if there's anything I could do or provide to help, feel free to let me know

The warning is not a major issue, for now, but thanks for reminding me of it.

I'm getting this every time I log into my dedicated local server after upgrading from 1.0.21b to 1.0.22.

I've tried restarting my client and the server.

Here's my server.txt.
