Error when importing a non-syntactically correct crafting recipe

[DorkOrc]

{
    "type": "minecraft:smelting",
    "ingredient": {
        "item": "minecraft:structure_void"
    },
    "result": {
        "item": "minecraft:jigsaw"
    },
    "experience": 0.1,
    "cookingtime": 200
}

This happened

I know the syntax is wrong regardless, but it should probably not result in this ^^

What is the expected result according to you?

Just an empty string, or result just gets removed until something correct is written, not an invalid item object which gets displayed as [object Object].
