Page Without Valid React Component
Next.js found a page file that does not export a valid default React component, which breaks rendering and build analysis.
Error AtlasError Documentation and ResolutionObserved message
Page Without Valid React Component
Why it happens
- A page file exports named values instead of a default React component.
- A shared helper file was accidentally placed where Next.js treats it as a page.
- The default export does not return a valid React component.
How to fix it
- Add or correct the default export for the page component.
- Move non-page files into folders such as components or lib.
- If using custom page extensions, verify the extension configuration matches the file layout.
