/rpgitem give <item>. Doesn't work

Bug Report

/rpgitem give causes the feedback "Internal server error. Unable to run command"

Describe the Bug

I made an item and when I tried to give it to myself this happened. I thought I might have done something wrong so I followed the tutorial on the spigot page. It still didn't work. Is this a bug or do I have the brain capacity of a two-year-old?

A clear and concise description of what the bug is.

To Reproduce

Steps to reproduce the behaviour:

1. Follow guide on spigot page or make own item
2. Do /rpgitem give
3. Recieve the error message and get mad.

Expected Behavior

I expected to receive the item.

Additional Context

I am using this on minehut. Which could be the reason why the game is dying

It seems that Minehut is the issue here with the plugin. I tried using another server and it worked fine. :(
