[Help Wanted] .json.patch doesn't work (?)

[Disketaa]

.json.patch

{
"op": "add",
"path": "/features/2/-",
"value": "kubejs:ore_tin"
}

Trying to add ore patch to all biomes but after dump there is no tin patch at all. However when I renamed file to plains.json.patch it worked out but only for plains biome.

How can I patch all the biomes at one time?

Have you taken a look at the documentation on dynamic patches yet? It explains how to achieve this kind of thing (albeit removing a feature rather than adding one), although I suppose it could be somewhat clearer.

You'll need to make sure you have the pack.mcmeta part as described in the docs, with name_of_patch being the name of your patch file (e.g. add_tin for add_tin.json.patch). If you have any biome mods (or data packs) installed you'll also want to include their namespaces in the namespace array (e.g. [ "minecraft", "biomesoplenty", "terralith" ]). Finally, make sure your patch is in the patches folder of your data pack and that there's at least one file in your data pack for each of the relevant namespaces. Your data pack should look something like this:

TinDataPack
├ data
│ ├ terralith (or the namespace(s) of any other biome mods/data packs you have installed)
│ │ └ __dummy.json
│ └ minecraft
│   └ __dummy.json
├ patches
│ └ add_tin.json.patch
└ pack.mcmeta

// pack.mcmeta
{
  "pack": {
    "pack_format": 57, // or whatever version Minecraft is at these days
    "description": ""
  },
  "patched": {
    "format_version": 1,
    "patch_targets": [
      {
        "pack_type": "server_data",
        "patch": "add_tin", // or whatever the base name of your patch is
        "targets": [
          {
            "namespace": [ "minecraft", "terralith" ], // add or remove namespaces as needed (make sure you have at least one file in each namespace!)
            "path": [ { "pattern": "worldgen/biome/.*\\.json" } ]
          }
        ]
      }
    ]
  }
}

I imagine you'll also not want this ore to generate in other dimensions like the Nether or the End, in which case your options are somewhat limited. I think you'll either have to a) write test conditions which check for features in those dimensions (like nether_gold_ore or chorus fruit) or b) give up and write a biome modifier instead (if your mod loader happens to be NeoForge or Forge)
