What's the exact name of the regeneration arrow to be able to use it as a custom recipe?

I know how to create a datapack, but can't manage to find the exact name for the regeneration arrow as a result of a craft. Tried

"item": "minecraft:tipped_arrow{Potion:"minecraft:regeneration"}",

but didn't work. Thanks for your help!

There are 3 problems with your current code:

• minecraft:tipped_arrow does not exist. It should simply be minecraft:arrow with the Potion NBT tag.

• There has to be a space between minecraft:arrow and the { marking the start of the NBT tags.

• You can't nest quotes like that in JSON files. It makes the parser think you typed in two strings, minecraft:tipped_arrow{Potion: and } and that minecraft:regeneration is just random text. The easiest way is to simply put ' characters rather than " around minecraft:regeneration (or whatever potion you're using).

In the end, it should look like this:

"item": "minecraft:arrow {Potion:'minecraft:regeneration'}",
