AdminBro.bundle 错误 - 元素类型无效

Question

我尝试在 AdminBro 中为照片构建自定义组件： 在选项中：

const options = {
properties: {
    photo: {
        components: {
            edit: AdminBro.bundle("../../src/photo"),//the path is right !
        },
    },
},

};

照片编辑组件：

import React from "react";
const Edit = () => {
return <div>hello</div>;
 };
export default Edit;

和admin bro的创建条目：

AdminBro.UserComponents = {}
import Component1 from '../controllers/resources/photo'
AdminBro.UserComponents.Component1 = Component1

我不知道为什么我得到：

Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports. Check the render method of `BasePropertyComponent`.

检查BasePropertyComponent的渲染方法........
