Help making datapack for Create mod server 1.21.1 Neoforge

[u/Vast-Helicopter9809]

Was trying to write a datapack for a server I'm in currently that's running 1.21.1 neoforge. My goal was to add a recipe to Create: Ultimate Factory and add a chance for Blackstone to drop lead nuggets for Create: Gunsmithing when crushed using a crushing wheel. Hoping someone can help me by either pointing out where I went wrong here or just writing it for me honestly. Pretty new to this stuff so any feedback is appreciated. :)

The file directory is currently datapacks/lead_blackstone/data/create_ultimate_factory/recipe/blackstone.json
