Block facing when placed down?

I'm new to this myself, but from what I can gather, the blockstates JSON file define the direction to place a block in.

I copied the carved_pumpkin.json in net.minecraft.client.extra:1.18.1:

{
  "variants": {
    "facing=east": {
      "model": "minecraft:block/carved_pumpkin",
      "y": 90
    },
    "facing=north": {
      "model": "minecraft:block/carved_pumpkin"
    },
    "facing=south": {
      "model": "minecraft:block/carved_pumpkin",
      "y": 180
    },
    "facing=west": {
      "model": "minecraft:block/carved_pumpkin",
      "y": 270
    }
  }
}

Unfortunately I still can't get it to work, mine says "Unknown blockstate property: 'facing'"

Update:

The error is for all four directions. This works however:

{
  "variants": {
    "": {
      "model": "minecraft:block/carved_pumpkin",
      "y": 270
    }
  }
}

The reply to the following (old) post seems to be saying that blockstates don't work in Forge, is that true?

Could it be that my versions for things are wrong?

Good luck!
