Format for enchants?

[wildstoats]

Hello there. Either enchants aren't working quite right or I'm misunderstanding something. When I try to use the example from breakevents.json:

[
  {
    "playerhelditem": {
      "item": "minecraft:iron_pickaxe",
      "nbt": [
        {
          "tag": "ench",
          "contains": [
            {
              "tag": "id",
              "value": 34
            }
          ]
        }
      ]
    },
    "block": "minecraft:diamond_ore",
    "result": "allow"
  },
  {
    "block": "minecraft:diamond_ore",
    "message": "You cannot mine this!",
    "result": "deny"
  }
]

And then give myself an Iron Pickaxe with Piercing (id:34) using the following command:

/give @s iron_pickaxe{Enchantments:[{id:piercing,lvl:3}]} 1

I am unable to break the block due to Rule 1.

If I instead do this:

/give @s iron_pickaxe{ench:[{id:34,lvl:3}]} 1

Then I am able to break the block but AFAIK this isn't a valid enchant. If I mouse over the pickaxe it glimmers as if it's enchanted but doesn't report as Piercing III.

If I change the rules to the following:

[
  {
    "playerhelditem": {
      "item": "minecraft:iron_pickaxe",
      "nbt": [
        {
          "tag": "Enchantments",
          "contains": [
            {
              "tag": "id",
              "value": "piercing"
            }
          ]
        }
      ]
    },
    "block": "minecraft:diamond_ore",
    "result": "allow"
  },
  {
    "block": "minecraft:diamond_ore",
    "message": "You cannot mine this!",
    "result": "deny"
  }
]

Then the rules work as expected but fxcontrol shows the following error message in the game console:

FxControl Error: Bad expression 'piercing'!

Does this just need updated to allow for string tags as opposed to numeric values? I am using fxcontrol-1.18-3.0.0.jar on minecraft 1.18.1.
