Normally, if a json in datapack quote an invalid object, the file could not be loaded by minecraft, which equals the file does not exist.

But somehow, when it turns to a recipe ' "type": "minecraft:stonecutting" ', game will NOT verify whether the "result" is valid AT ALL! In other words, if a stonecutting recpie has an invalid result, minecraft would still regard it as a valid one, and will load it while automatically replace the invalid result with "minecraft:air", item.

The bug exists since introduced in 1.14. Capture is in 1.19.3, and the json is the recipe itself.

一般来说，如果数据包的json文件引用了无效的对象，那么这个文件无法被游戏加载，等同于不存在。

但是，在切石的配方中，游戏不会检测产物的合法性。换句话说，如果切石机的产物不存在，游戏仍然会视为是一个合法的配方，并且能够加载，其产物会自动替换为空气。

这个bug在1.14引入以来，至目前的最新版1.19.3为止一直存在。图为1.19.3的截图，附件为对应的无效配方。
