[Bug] not work on mohist 1.20.1

[adamejzak]

API version

2.5.0

Server software and version

Mohist 1.20.1 banner-1.20.1-800

Steps to reproduce

When I use SignGui on Mohist, I get an error, but when I use it on Spigot, everything works.

Expected behaviour

that it would work

What is actually happening?
