I had upgraded my mod to use the json recipes as part of the 1.12.X port and I believe they were working find when I first tested them. I used to use a custom recipe handler in the pre-1.12 versions.

However I've recently retested due to a bug report (StoredEnchandments needing to use shorts in the nbt) and seem to be getting the same output item for all the recipes that have the all the same ingredients, apart from a different enchanted book.

These recipes all use vanilla enchanted books as an ingredient.

JEI shows the correct output for the input ingredients, but the vanilla crafting table gives the wrong output.

 

I've updated to using Forge 14.23.1.2554 with no difference.

 

eg. 

rate 1 upgrade (metadata 0) - factory base + t1 upgrade core + power I enchanted book -> output is decapitate I (metadata 12)

looting 1 upgrade (metadata 3) - factory base + t1 upgrade core + looting I enchanted book -> output is decapitate I (metadata 12)

All the recipes with enchanted books output the same item but with different metadata. 

 "result": {
    "item": "woot:upgrade",
    "data": 3
  },

 

 

This is the format of ingredient I was using successfully(?) before, probably during 1.12 development rather than 1.12.1 or 1.12.2.

    {
      "type": "minecraft:item_nbt",
      "item": "minecraft:enchanted_book",
      "nbt": {
        "StoredEnchantments": [
          {
            "id": 21,
            "lvl": 1
          }
        ]
      }
    }

 

I've also tried using the vanilla string nbt version of this with the same results.

     {
       "type": "minecraft:item_nbt",
       "item": "minecraft:enchanted_book",
      "nbt": "{ StoredEnchantments: [ { id: 32s, lvl: 1s } ] }"
     }

So I think I've solved this, because my upgrade to Forge 14.23.1.2554 didn't fully refresh the dev environment.

Now that I'm definitely running with the latest forge, it looks like my recipe issues are not happening anymore and I've getting unique items.

 

So I'll pass on my apologies for wasting peoples time.

(No matter how much you check, you always miss the obvious!)

 

 

Man you're a legend! 

I was searching the wide web on how to get enchanted books into crafting recipes in json format and stumbled upon your post. The format 

{
      "type": "minecraft:item_nbt",
      "item": "minecraft:enchanted_book",
      "nbt": {
        "StoredEnchantments": [
          {
            "id": minecraft:sharpness,
            "lvl": 1
          }
        ]
      }
    }

still works on 1.16.5 forge, so thanks alot!
