can somebody help me with fixing the error?

You know where it says “do not report this to paper”…

But it means your server doesn’t have enough resources, upgrading your server should fix this.

yeh but we not wanting to report this to paper we’re just trying to understand what this error means and what to do about it considering it says it’s not a crash… yet it crashes my server. Sooooo

Did you insert a shulker box to y 257?

Normaly its really a crash btw
