[material-ui] Not working after upgrading Next.js to 14.0.4. Error: Element type is invalid. #40214
Description
Duplicates
- I have searched the existing issues
Latest version
- I have tested the latest version
Steps to reproduce 🕹
I created a sample repository here.
Steps:
- Create a new Next.js project:
npx create-next-app@latest(select theapp routerandtypescript), - Install Material-UI:
npm install @mui/material @emotion/react @emotion/styled @mui/material-nextjs @emotion/cache - Wrap the children in the root layout with the
AppRouterCacheProvider, as it is described here, - Add any
@mui/materialcomponent above the{children}in the Root layout (I added the<CSSBaseline />but also tried with anotherTypography):
export default function RootLayout({
children,
}: {
children: React.ReactNode;
}) {
return (
<html lang="en">
<body className={inter.className}>
<AppRouterCacheProvider>
<CssBaseline />
{children}
</AppRouterCacheProvider>
</body>
</html>
);
}
- Add any
@mui/materialcomponent to theapp/page.tsxfile. I triedBoxandTypography.
import Image from "next/image";
import styles from "./page.module.css";
import { Box, Typography } from "@mui/material";
export default function Home() {
return (
<main className={styles.main}>
<Typography>Hello!</Typography>
</main>
);
}
- Run the project:
npm run dev - You will see the following error:
Note: Somehow it works when I remove all
@mui/material-uicomponents from the layout (CSSBaselinein the above example) - but it should be allowed and normal to have mui components in the root layout.
Current behavior 😯
The error:
Error: Element type is invalid. Received a promise that resolves to: undefined. Lazy element type must resolve to a class or function.
