Java 1.20.4

Got a Resource / Datapack I am making.
I have 1 .json model called flam1.json
It is saved in the correct animals folder

In the Datapack, in models/items is:
flint.json

the notepad coding for the flint is:

{ "parent": "item/generated", "textures": { "layer0": "item/flint" },

"overrides": [
{"predicate": {"custom_model_data":42}, "model": "animals/flam1"}
]
}

If I summon an armor stand with the added code: tag:{CustomModelData:42}
The armor stand correctly has the model instead of the flint.

In the same models/items folder, I copied & renamed it:
coal.json

{
"parent": "item/generated",
"textures": {
"layer0": "item/coal"
},

"overrides": [
{"predicate": {"custom_model_data":99}, "model": "animals/bunny1"}
]
}

But the summoned armor stand with a coal just gives me the purple/black block.

What am I doing wrong?
