将 .gltf 文件导入 threejs 时出错（在 expo 中）

Question

将 .gltf 文件导入 threejs 时（在 expo 中），出现以下错误：

Error: Event {
  "isTrusted": false,
}

我在 Expo React Native 项目中使用来自三个（/examples/jsm/loaders/GLTFLoader.js）的 GLTFLoader，代码如下：

loader.load(
      "../body.gltf",
      (gltf) => {
        console.log("Object: ", gltf);
        scene.add(gltf.scene);
      },
      (progress) => console.log("Progress: ", progress),
      (err) => console.log("Error: ", err)
    );

我的权限中是否有我不知道的内容，是在 expo 中还是其他内容？

正在加载资产：

  useEffect(() => {
    (async () => {
      const assets = [
        Asset.fromModule(require("./assets/abductors.gltf")),
        Asset.fromModule(require("./assets/abs.gltf")),
        Asset.fromModule(require("./assets/adductors.gltf")),

        Asset.fromModule(require("./assets/traps.gltf")),
        Asset.fromModule(require("./assets/triceps.gltf"))
      ];

      let body = new THREE.Scene();

      for (let i = 0; i < assets.length; i++) {
        await assets[i].downloadAsync();
        const loader = new GLTFLoader();
        loader.load(
          assets[i].uri || "",
          (gltf) => {
            assets[i] = gltf.scene;
            body.add(gltf.scene);
          },
          (xhr) => {
            console.log(`${(xhr.loaded / xhr.total) * 100}% loaded`);
          },
          (error) => {
            console.error("An error happened", error);
          }
        );
      }

      setBody(body);
    })();
  }, []);

显示它们：

const _onContextCreate = async (gl) => {
    const { drawingBufferWidth: width, drawingBufferHeight: height } = gl;

    let renderer = new ExpoTHREE.Renderer({ gl });
    renderer.setSize(width, height);
    renderer.setClearColor(0xffffff);

    let camera = new THREE.PerspectiveCamera(80, width / height, 0.01, 1000);
    camera.position.z = 5;

    let scene = new THREE.Scene();

    const light = new THREE.PointLight(0xffffff, 1, 500);
    light.position.set(5, 10, 10);
    scene.add(light);

    scene.add(body);
    body.position.set(0, -2, -5);
    body.scale.set(1.2, 1.2, 1.2);
    body.rotation.set(0, 0, 0);

    [...]
  };

return (
    <Model
      _onContextCreate={_onContextCreate}
      body={body}
      setActiveMuscles={setActiveMuscles}
      onChangeStroke={onChangeStroke}
