The bug
When creating a recipe with invalid characters in the item
field, the game will fail to reload the data packs. It is understood that these characters should not be there, however the game should still reload the rest of the data pack.
Example: The following will cause the game to fail reloading the data packs:
"item": "minecraft:fire_charge{Enchantments:[{id:"minecraft:sharpness",lvl:1}]}"

A detailed walkthrough of the error, its code path and all known details is as follows:

"item" expects an ID, not additional NBT. NBT with recipes isn't supported yet.
Edit: Though it probably shouldn't crash.
