When I use the code:

    "data": [{
        "name": "Todabonium Ingot",
        "oreDictNames": ["todabonium"],
        "maxStackSize": "64",
        "burnTime": "0",
        "rarity": "common",
        "enchanted": "true"
    }]

I get a item name issue:
Item is called: item."name".name I would wish it would only write "name" (see image below)
Am I doing something wrong? I get the same for every item I create with the mod.

As this mod has full translation support, you must add language entries for your items. See https://github.com/tterrag1098/CustomThings/wiki/Adding-Icons-and-Lang-Files .

I would recommend the "name" field being something simpler and without spaces, but it is not a strict requirement.

Now I understand and it fully makes sense. Thanks @tterrag1098
