I have a few recipes and none of them are working

here is one of them

{
    "type": "minecraft:crafting_shaped",
    
    "pattern":
    [
        "SSS",
        "SFS",
        "SCS"
    ],
    
    "key":
    {
        "S":
        {
            "item": "minecraft:stone"
        },
        "C":
        {
            "item": "thelostportal:catalyst"
        },
        "F":
        {
            "item": "minecraft:furnace"
        }
    },
    
    "result":
    {
        "item": "thelostportal:non_energy_forge",
        "count": 1
    }
}

I think I wrote the recipe right but it isn't working. Is there something I forgot to do?

What version of Minecraft? If not 1.13, then you need the data parameter on the stone entry.

Also, if you are using version 1.13.2, the recipes folder moved to resources/data/modid/recipes.

If this is not the case, then there is something wrong in your recipe json. The log should tell you what went wrong.
