I would suggest deleting and retyping the line it is pointing to, it looks like there's some kind of characters in there between the method name and the curly brace that don't belong, as opposed to a simple space.
That's because you just copy-pasted what I put there..
Caused by: java.io.FileNotFoundException: modid:models/block.json
You have to put YOUR modid where modid is, and YOUR block name where block is.
{
"parent": "ffactory:block/copper_chest"
}
for example... ^
Looks like an asset problem. https://github.com/Gamerstone/FFactory/blob/master/resources/assets/ffactory/models/item/copper_chest.json#L1-L6
https://github.com/Gamerstone/FFactory/blob/master/resources/assets/ffactory/models/item/iron_chest.json#L1-L6
Your item model JSON can simply be: (For blocks!)
{
"parent": "modid:block"
}
If it's an item texture, then your current method is just fine.
