Minecraft Version

1.20.1

The Issue

Server crash when adding skills to player via command block & Datapack

[Works when doing it manually with a command, but not with commands!]

Client Forge version: 1.20.1-forge-47.3.0
Server Forge version: 1.20.1-forge-47.3.0

Crash logs:

When adding skill with Datapack function:
crash-2024-10-08_00.22.25-server.txt

When adding skill with com
crash-2024-10-08_00.20.11-server.txt
mand block:

Tested with only Epic Fight installed, no other mods:
crash-2024-10-08_00.25.59-server.txt

Steps to Reproduce

The simplest way to reproduce this error would be to try giving yourself a skill with a command block, example: /epicfight skill add @p passive1 epicfight:berserker

And the other way would be to make a datapack with a function which gives the player a skill when executed.

I just tested the issue on all Epic Fight versions, and found out this bug doesn't happen on versions without the Datapack Editor feature.

Last working version: Epic Fight 20.7.4

Same type of crash to #1815

Fixed in 20.9.3
