I know there's a thread but it's a bit polluted probably be ignored by others.

I have this project from the image which is deployed to render but they shut it down after 20min so I wanna try Vercel.

The project is being deployed succesfully but I got a 404 not found error. I understand I need a vercel.json file in the root or something?? I used typescript, also trpc for the endpoints so I could use Zod for validation.

Any help will be appreciated
