im creating the glue datapack recipes for my own personal "modpack" and I want to disable the builtin ae2 compatability recipes for the assembler, however i can't do the usual datapack trick of creating a recipe with an input of air as it throws an exception when loading the recipe

Alternatively allow an empty json object to remove the recipe (which also doesn't work, as it throws about the eu & duration keys being missing)

Use KubeJS or something similar to remove recipes.

You can use {"neoforge:conditions": {"type": "neoforge:false"}} (or something like that) to disable a recipe.
