Could not pass event to Skript

[rustedst]

I have this script which uses skript-mirror:

Spoiler: Script

on break:
    set {_bl} to event-block
    set {_tip} to {_bl}.getBreakSound().getSoundType()
    send "%{_tip}% a" to player

But it gives that error in console when the event is triggered:

Maybe ask the developer directly, since it's a issue with the addon skript-mirror ¯\_(ツ)_/¯

You're trying to import a class from Paper, even though you're running Spigot
