I already know how to go into the heart recipe thing but I just really need to know how to set it up

I have tried this but doesn't work

{
"enabled": true,
"shaped": true,
"outputAmount": 1,
"recipe": [
"DTD",
"TET",
"DTD"
],
"D": {
"item": "Minecraft:diamond_block
},
"E": {
"item": "Minecraft:elytra"
},
"T": {
"item": "minecraft:totem_of_undying"
}
}
}

{
"enabled": true,
"shaped": true,
"outputAmount": 1,
"recipe": [
"DWD",
"TNT",
"DTD"
],
},
"W": {
"item": "Minecraft:wither_skeleton_skull"
},
"D": {
"item": "Minecraft:diamond_block"
},
"T": {
"item": "minecraft:totem_of_undying"
},
"N": {
"item": "Minecraft:netherite_ingot"
}

also tried it like this

take the default heart recipe and just add to it, you removed a lot of needed things such as brackets, arrays etc, just reset it (delete it) and rewrite it, this time making sure you don't delete anything

K, thank u it works :)

alr i'll try
