uim3.5升级到umi4.3 路由渲染页面报错：Element type is invalid. Received a promise that resolves to: [object Object]. Lazy element type must resolve to a class or function.

[Taurues]

开发环境：
"@umijs/max": "^4.3.35",
"@types/react": "^18.3.0",
"@ant-design/pro-components": "2.7.19",

config/config.js 文件配置项

export default defineConfig({ hash: true, targets: { ie: 11, }, routes, theme: { 'root-entry-name': 'variable', }, ignoreMomentLocale: true, fastRefresh: true, model: {}, initialState: {}, title: '系统', layout: { locale: true, ...defaultSettings, }, request: {}, access: {}, presets: ['umi-presets-pro'], esbuildMinifyIIFE: true, requestRecord: {}, keepalive: [/./], tabsLayout: {}, });

app.js layout配置
export const layout = () => { return { avatarProps: {...}, route: { routes: [ { name: "首页", icon: <SmileOutlined />, component: "./Welcome", path: "/welcome", }, ], }, childrenRender: (children) => { // if (initialState?.loading) return <PageLoading />; return ( <> {children} 如果这里直接写<div>2234</div>就可以正常渲染出2234，用children就报错 </> ); }, } }
报错如图：
