The datapack installed is loaded and can be checked using /datapack list but the functions doesn't actually work or show up when typing{{ /function}}
This is not related to the changes made in 24w19a where folders are renamed to singular form since the datapack only include tags/functions and they were not mentioned to be changed in the changelog. This issue is seen from snapshot 24w21a to the current 1.21-pre4. Updating the pack version to the corresponding latest versions didn't seem to work as well. Below is a simple datapack only using functions
EDIT: Nevermind I read the changelog of 24w21a
Hey, i just had this same exact issue, but turns out in 24w21a, they changed the naming of some folders, the changelog says:
Some registry types that used legacy datapack directory names (based on plural name of element) have been renamed to match registry name
Affected directories:
structures -> structure
advancements -> advancement
recipes -> recipe
loot_tables -> loot_table
predicates -> predicate
item_modifiers -> item_modifier
functions -> function
tags/functions -> tags/function
this should fix it, and this ticket should be closed as Invalid.
glad I'm not the only one who made this mistake though xD
