[SOLVED] [1.16] null key in entry, Failed to load datapacks

[kiou.23]

I have a class that extends IRecipe, with it's own serializer and builder.

I'm registering the Serializer with a deferredRegister, and I'm registering the recipe type by calling IRecipeType.register in the registry event for the recipe serializers.

I'm generating a file using the recipe builder, it works fine. but whenever I try to load a world it gives the following error:

https://gist.github.com/jvcmarcenes/0ef3c7b8eeabf94efce04fd40215cafa

 

this is the recipe file (generated [main]/resources/data/minecraft/recipes/diamond_mod_recipe.json):

{
  "type": "tca:mod_shaped",
  "energy_cost": 100,
  "pattern": [
    "ddd",
    "dgd",
    "ddd"
  ],
  "key": {
    "d": {
      "item": "minecraft:dirt"
    },
    "g": {
      "item": "minecraft:gold_block"
    }
  },
  "result": {
    "item": "minecraft:diamond"
  }
}

 

and this is the generated file fot the criterion (generated [main]/resources/data/minecraft/advancements/recipes/misc/diamond_mod_recipe.json):

{
  "parent": "minecraft:recipes/root",
  "rewards": {
    "recipes": [
      "minecraft:diamond_mod_recipe"
    ]
  },
  "criteria": {
    "has_item": {
      "trigger": "minecraft:inventory_changed",
      "conditions": {
        "items": [
          {
            "item": "minecraft:gold_block"
          }
        ]
      }
    },
    "has_the_recipe": {
      "trigger": "minecraft:recipe_unlocked",
      "conditions": {
        "recipe": "minecraft:diamond_mod_recipe"
      }
    }
  },
  "requirements": [
    [
      "has_item",
      "has_the_recipe"
    ]
  ]
}

• Your Mod ID is too short and not unique.

Yeah, I've been told, I'l change it later

• This error happens if your IRecipe returns null in getType.

I added the IRecipe before the RecipeType, so I made it return null and forgot about it...
