Unexpected token h in JSON at position 0 with

[jinbread]

Hi, I am pretty new to react three fiber and now I am having trouble deploying a simple 3D model.
What I want to achieve is very simple. Just load a 3D model to the main page.
Here is the code and it looks working on the Codesandbox.

function Model(props) {
  const { scene } = useLoader(GLTFLoader, "glbtest.glb");
  useFrame(() => (ref.current.rotation.x += 0.01));
  const ref = useRef();

  return (
    <group {...props} dispose={null} ref={ref}>
      <group
        position={[-150, 0, 200]}
        rotation={[0, 0.2, 0]}
        scale={[0.3, 0.3, 0.3]}
      >
        <primitive object={scene} />
      </group>
    </group>
  );
}

export function GlitchPage() {
  return (
    <Canvas camera={{ position: [-100, -130, -50] }}>
      <ambientLight intensity={1} />
      <pointLight position={[-400, -400, -400]} />
      <Suspense fallback={null}>
        <Model />
      </Suspense>
    </Canvas>
  );
}

https://codesandbox.io/s/scdw-2020-web-npb04?file=/src/App.js:658-1340

But when I try to deploy this on Vercel,
It never works and shows error like "web.js:78 Unexpected token h in JSON at position 0"
https://scdw-2020.vercel.app/

I separated the code from the original source and deployed somewhere else and this works.
https://codesandbox.io/s/affectionate-lehmann-vj5kl?file=/src/App.js:206-888
So I guess something is crashing on the original code, but hard to guess what it is.

Can I get some advice to solve this?

Thank you.

where's the code? that warning most likely means the path is wrong - it comes from the threejs loader, which is parsing a html 404 page not found error

I thought I added the code and the link. I just updated the details. Thank you.

looks like a path issue issue. try "/glbtest.glb" or "/public/glbtest.glb" this could change between bundlers like csb and next. the vercel site you posted isnt online so i cant check. the csb isnt that useful because it works and that makes it certain that this is a bundling/hosting relating issue.
