React ThreeJs not showing actual model when loading

Question

I'm trying to load a model in gltf format using react three fiber but it shows somewhere black somewhere white not the actual model. How can I fix that?

This is my actual model image :

this is what I got when I loaded the model:

I used ambient light.directional light but nothing works. Tried with different models but the result is same. Sometimes it shows black version of the model.

Here is my code:`

import { Suspense } from "react";
import { Canvas } from "@react-three/fiber";
import { OrbitControls, Stats } from "@react-three/drei";

import Model from "./Model";

export default function App() {
  return (
   
      <Canvas style={{ height: 800, width: 800 }}>
        <OrbitControls
          enableZoom={false}
          rotateSpeed={2}
          autoRotate={true}
          autoRotateSpeed={5}
        />
        <ambientLight intensity={0.6} />
        <directionalLight intensity={0.5} />
        <Suspense fallback={null}>
          <Model />
        </Suspense>
      </Canvas>
  
  );
}

`

Here is the model code I generated using gltsjsx:
