I'm having a problem where I've created a simple crafting recipe that takes in redstone dust and 4 iron ingots and returns an iron ingot (just for testing purposes). I have the file in my resouces/data/(modid)/recipes directory. However, the recipe does not work and I get no output when actually using a crafting table. Any help would be useful.

At result, change:

"id": "minecraft:iron_ingot"

to

"item": "minecraft:iron_ingot"

I managed to figure it out on my own. The result should be id, however the recipes folder should have been named recipe. Thank you anyways though
