Tchest commands like /tchest set don't work

[ARCTIC314]

Hello!
I have LWC plugin on the server installed like treasure chest.
When i do /cremove i try to do /tchest set and nothing happens even the chat says nothing. (I aim at the chest) Everything i do good.
In the console i saw some error i will paste it below:
Failed to invoke command method "unlimited" of class "com.mtihc.minecraft.treasurechest.v8.plugin.TreasureChestCommand"java.lang.reflect.InvocationTargetException
If u might know what to do i will really appreciate it!

I don't know much about the LWC plugin. Are you sure it's even related to the problem? Did /tchest set work before? Does it work when you use /tchest set on a freshly placed chest?

Also, there should be more information about the error. Make sure you copy the whole thing from your log file.
