Im trying to patch into nugget.json to allow malachite and native copper to be powdered in the pulverizer, and ive tried about 100 different things but none of them work. The game either crashes upon loading into the test world or crashes and spits out the same error:

I got this patch to work and allow for claystone to be grinded into powder in the quern:
[
{
"op": "addmerge",
"path": "/grindingPropsByType/stone-claystone",
"value": {
"groundStack": { "type": "item", "code": "kaoliniteyay:crushedclaystone", "stacksize": 1 }
},
"file": "game:itemtypes/resource/stone.json"
}
]
but for the life of me I CANNOT figure out how to make this patch work:
[
{
"op": "addmerge",
"path": "/crushingPropsByType",
"file": "game:itemtypes/resource/nugget.json",
"value": {
"nugget-nativecopper": {
"crushedStack": { "type": "item", "code": "kaoliniteyay:copperpowder" },
"quantity": { "avg": 1.5 },
"hardnessTier": 2
},
"nugget-malachite": {
"crushedStack": { "type": "item", "code": "kaoliniteyay:copperpowder" },
"quantity": { "avg": 1.5 },
"hardnessTier": 2
}
}
}
]
I've tried so many different things. Not even straight up copy pasting the base game crushing properties for lead nuggets and then changing the items it refers to so that it matched the copper powder worked. If anyone needs me to give anything else to figure out, please ask. I'm nearing my limit with this bs.
