The Issue

crash-2024-09-18_16.15.19-server.txt
Using the function command in the command block to execute epicfight skill add @p identity epicfight:revelation will causes the server to crash.
This is a big bug, causing my map to not work properly.

Steps to Reproduce

1. Create a datapack
2. Add this command epicfight skill add @p identity epicfight:revelation
3. Place a command block and type function test:test
4. Activate command block
5. Server crash
   

Won't crash if you type function test:test in the chat. Won't crash if you are in Singleplayer. Only crash when in a server using a command block to execute it.

Fixed in 20.9.3
