A Question About Dungeon Loot

I tried it immediately after I received your reply.But there are some strange phenomena.
I wrote in MineTweaker’s scripts to delete items from the treasure chest.But it didn’t work properly.
But when I removed GT6, it worked.
These are the errors when installing GT6:

ERROR: Error executing test.zs: null

And these are what I wrote down:

vanilla.loot.removeChestLoot("dungeonChest", <*>);

Thank you for your response to the question of creating the world. But it may be too difficult for me. I may need to study hard.^ ^
