my texture doesn't load with atlas

I have a model inassets/ancient_artifacts/models/entity/artifact_golem.json 
{
  "credit": "Made with Blockbench",
  "texture_size": [96, 96],
  "textures": {
"0":"ancient_artifacts:entity/artifact_golem",
"particle":"ancient_artifacts:entity/artifact_golem"
...``` but the texture in ``assets/ancient_artifacts/textures/entity/artifact_golem.png`` doesn't load so I made a texture atlas in ``assets/ancient_artifacts/atlases/entity.json``  ```json
{
    "sources": [
        {
            "type": "directory",
            "source": "entity",
            "prefix": "entity/"
        }
    ]
}``` but my texture still doesn't load (I think it's a problem with the atlas since when I dump debug textures my atlas texture isn't there
