Unable to resolve texture due to upward reference: #all in minecraft:block/cube_all

{
    "parent": "block/cube_all",
    "textures": {
        "": "subterranean_creatures_mod:blocks/simie_cobblestone"
    }

Seems pretty obvious to me. You have your texture named “” in your model, but the model parent (block_all) requires a texture named “all”
