Based on the official docs (https://nextjs.org/docs/app/building-your-application/routing/error-handling#nested-routes) I understood that error.js/tsx file also covers the page.js/tsx file within the same folder, but not the layout.js/tsx. Hoverer, in practice, adding an error.js/tsx file in the same folder with page.js/tsx did not catch any errors within that page.js/tsx file, but rather I had to add error.js/tsx file in the parent directory, in order to catch errors in the nested page.js/tsx. Can someone confirm that the docs are indeed incorrect?
