How could I better structure the files to avoid this error?

Can you show the whole folder structure? From the screenshot it looks like you don't have an entry point for / (your home page) nvm idea-mangagement being highlighted threw me off, you do have an entry point which is the page.tsx you have in the screenshot

Ah okay there is the issue, you have two page.tsx's at the same route segment level

(app) is purely organizational, it doesn't affect the URL path so the page.tsx inside (app) is still your entry point / the one outside are conflicting with the ones inside or vice versa depending on the behavior you are looking for

So should I delete src/page.tsx, keep src/layout.tsx and keep the layout within the groups, with each group not having page.tsx?

Oh, thanks!

The layouts are fine

Only issue is the page.tsx files

I see, I will fix it

Thanks!

No problem
