❗ Checklist

• I am using the official english version of Slimefun and did not modify the jar.
• I am using an up to date "DEV" (not "RC") version of Slimefun.
• I am aware that issues related to Slimefun addons need to be reported on their bug trackers and not here.
• I searched for similar open issues and could not find an existing bug report on this.

📍 Description

When Slimefun4 is loading in versions prior to 1.19 this exception will be raised

This probably also happens in lower versions than 1.17

It doesn't really matter since it doesn't affect anything else but exceptions should be fixed if possible

This server is running Pufferfish version git-Pufferfish-22 (MC: 1.17.1)

📑 Reproduction Steps

1. Use any version prior to 1.19
2. Check console as Slimefun is loading

💡 Expected Behavior

Error doesn't exist
