I want to generate a chest with my loot table. This works fine when i use a loot table from my assets. But is there a way to spawn a chest with a loot table from the config folder?

 

Edit: I just found the LootTableLoadEvent. Could i just pass the loot table from the config folder when the loot table from my mod is loaded?

The event seems to work but i don't know how i can get a LootTable from a String. I mean i have the content of the loot_table.json file in the config folder as String but how can i generate a LootTable out of it?

I haven't touched loot tables yet in any of my mods, but I just found this inside the LootTable class:
 

    public static class Serializer implements JsonDeserializer<LootTable>, JsonSerializer<LootTable>
        {
            public LootTable deserialize(JsonElement p_deserialize_1_, Type p_deserialize_2_, JsonDeserializationContext p_deserialize_3_) throws JsonParseException
            {
                JsonObject jsonobject = JsonUtils.getJsonObject(p_deserialize_1_, "loot table");
                LootPool[] alootpool = (LootPool[])JsonUtils.deserializeClass(jsonobject, "pools", new LootPool[0], p_deserialize_3_, LootPool[].class);
                return new LootTable(alootpool);
            }

            public JsonElement serialize(LootTable p_serialize_1_, Type p_serialize_2_, JsonSerializationContext p_serialize_3_)
            {
                JsonObject jsonobject = new JsonObject();
                jsonobject.add("pools", p_serialize_3_.serialize(p_serialize_1_.pools));
                return jsonobject;
            }
        }

Just don't ask me how to use it

If you find existing usages of the deserialize method, you might be able to figure out how to use it correctly.

Now i got this:

	private static final Gson GSON_INSTANCE = (new GsonBuilder()).registerTypeAdapter(RandomValueRange.class, new RandomValueRange.Serializer()).registerTypeAdapter(LootPool.class, new LootPool.Serializer()).registerTypeAdapter(LootTable.class, new LootTable.Serializer()).registerTypeHierarchyAdapter(LootEntry.class, new LootEntry.Serializer()).registerTypeHierarchyAdapter(LootFunction.class, new LootFunctionManager.Serializer()).registerTypeHierarchyAdapter(LootCondition.class, new LootConditionManager.Serializer()).registerTypeHierarchyAdapter(LootContext.EntityTarget.class, new LootContext.EntityTarget.Serializer()).create();
	
	@SubscribeEvent
	public static void loadLootTable(LootTableLoadEvent event) {
		if (event.getName() == TileEntityChestArmor.LOOT_TABLE) {
			File f = new File(CrystalicVoid.configFolderLoot + "/chest_armor.json");
			if (f.exists() && f.isFile()) {
				String s = null;
				try {
					s = Files.toString(f, StandardCharsets.UTF_8);
				} catch (IOException e) {
					e.printStackTrace();
				}
				event.setTable(GSON_INSTANCE.fromJson(s, LootTable.class));
		}
	}

But it just says

Invalid call stack, could not grab json context!

The json loot table that i try to load is fine. So someone has any idea?
