I've made the following changes to fix the error:

1. Renamed the component exports to follow Next.js App Router conventions:

   • Changed ComponentDetail to Page in the component detail page
   • Changed CategoryPage to Page in the category page

2. Added necessary layout files:

   • Root layout (app/layout.tsx)
   • Category layout (app/category/[slug]/layout.tsx)
   • Component layout (app/category/[slug]/[componentId]/layout.tsx)

These changes ensure that:

• All components are properly exported
• The file structure follows Next.js App Router conventions
• The routing hierarchy is maintained

The error should now be resolved. Would you like me to make any additional changes?

I've made the following changes to fix the error:

1. Created a new useCategory hook in app/hooks/useCategory.ts that:

   • Defines the Component interface
   • Provides mock data for different categories
   • Handles loading and error states
   • Returns components for the specified category

2. Updated the category page to:

   • Import and use the useCategory hook
   • Handle loading and error states
   • Display components from the hook
   • Maintain all existing functionality
3. Added proper TypeScript types and interfaces

The error should now be resolved. The page will:

1. Load components based on the category slug
2. Show a loading state while fetching data
3. Display an error message if something goes wrong
4. Render the component grid when data is available

Would you like me to make any additional changes?
