I got this error message in oxide log file. Its normal?

send your config file

Config file

UltimateLocker.json

Explain to me when this problem occurs, in detail.
What you were using, where you were positioning the locker, etc.

I haven't fixed yet what action causes the error. I found it when I was looking through the log for the day. But I still have a problem that another player can't install codelock on a generated machine in Spawn everything.

Hi, I'm doing some tests to try to replicate the problem.

I couldn't replicate the problem.

Are you still getting these kinds of errors?

Hi, I haven’t noticed any such errors so far. Players haven’t reported any specific problems yet. I haven’t encountered any issues myself either.
The only thing that caught my attention was an error I found in the logs — I thought maybe this is a problem you’re aware of and it’s not only happening to me.
If I discover anything, and it’s important to you, I’ll let you know.

The only idea I can think of is that someone was trying to codelock an entity, and it disappeared immediately afterwards. Perhaps another player on the team was removing it while another player was codelocking it.
If it happens again, please let me know with a new ticket. In the meantime, if I find the cause, I'll fix it.
Thanks
