The wiki says:
Removed attribute ID prefixes such as generic.. Changed formats of data components, loot tables and predicates. Added new data components, loot tables and item tags. Added key input predicate. Added crafting_transmute recipe type. Renamed enchantment effect damage_item to change_item_damage
No mention of changes to format for recipes
1.21.2 page:
Recipes
The crafting_special_suspiciousstew recipe type has been removed.
The format used for recipe ingredients has been simplified and aligned with other fields that accept item lists (like item predicates):
For items: { "item": "<item id>" } now becomes "<item id>".
For tags: { "tag": "<tag id>" } now becomes "#<tag id>".
Lists of items are still allowed, but tags can no longer appear in such list.
Remaining restrictions:
minecraft:air can't appear anywhere in ingredient.
ingredient must have at least one tag or item.
Fields template, base and addition in smithing_transform and smithing_trim recipes are now optional instead of accepting empty list.
Mojira is not a troubleshooting forum for datapacks, the error is included at the bottom of your report, and clearly outlines the problems with your datapack.
