I’m using a Next.js app with the app directory structure. I have a dynamic projects page

projects/[slug]/page.tsx.

When I run the project on localhost, it works perfectly. However, when I upload it to Vercel and click a dynamic route, it always results in an error (not found).

I tried to create a static page under the projects folder:

projects/test/page.tsx

This works perfectly.

However, when I visit this link on Vercel mydomain/projects/[slug] it shows me the content, but it no longer works on localhost.
