如何修复Firebase中TypeError: can't access property 'isRoot', location is undefined错误？

TypeError: can't access property "isRoot", location is undefined

使用SvelteKit框架开发，已知location是浏览器对象，已经通过onMount调用、$app/environment检查确保在浏览器环境中执行代码，但仍然触发上述错误。定位到错误由以下调用listAll的代码导致：

listAll(filesRef).then((list)=>{
    list.items.forEach(item=>{
        files.push({
            filetype:item.name.split(".").at(-1).toString(),
            name:item.name
       });
    });
});

补充说明：files是一个对象数组，每个对象包含filetype（文件后缀）和name（文件名），最终会将这个数组渲染为页面列表。
