hello so im developing a forge mod and i was updating from 1.21.1 to 1.21.3 and all my recipes jsons stopped working. i looked almost everywhere but i just could not fint the answear could you please help me thanks for any kind of responce in advance

my error:

i connot provide the error because the forum kept blocking my post for anti spamming but it was basicly Failed to parse either. First: Not a string: {"item":"minecraft:coal"}; but for more items

my json(note that this is just my test json i used when my stuff stopped working):

{
  "type": "minecraft:crafting_shaped",
  "category": "misc",
  "pattern": [
    "AAA"
  ],
  "key": {
    "A": {
      "item": "minecraft:coal"
    }
  },
  "result": {
    "item": "minecraft:iron_ingot",
    "count": 1
  }
}

You might want to check how you’re registering the capability provider — this often causes the issue you’re describing.

I ran into something similar recently while working on a Forge 1.20.x mod. Making sure registration happens at the correct lifecycle event fixed it for me.
