3D scene doesn’t have shadows even though I enabled castShadow and receiveShadow

Enter image description here

Hi,

I have an issue with my shadow. I am enabling the shadow in the code, but I don’t know why my 3D model is not receiving this shadow. You can see the image or the link Codesandbox Sunlight

Model.js

return <primitive object={scene} receiveShadow />;

Scene.js

  <directionalLight
    intensity={0.5}
    castShadow // highlight-line
    shadow-mapSize-height={512}
    shadow-mapSize-width={512}
    position={calc}
  />
  <Model />
  {/* Plane just to see the shadow - I will remove it later */}
  <Plane
    receiveShadow // highlight-line
    rotation={[-Math.PI / 2, 0, 0]}
    position={[0, -10, 0]}
    args={[100, 100]}
  >
    <meshStandardMaterial attach="material" color="white" />
  </Plane>

I enabled receiveShadow and castShadow
