Failing to get the deployment for my monorepo working ??

I'm trying to deploy my monorepo setup, using turborepo. Here is the project i'm trying to deploy https://github.com/vercel/turborepo/tree/main/examples/with-tailwind on railway but can't get the links to work. Created two empty service sand customised the start and build commands. The deployment is passing through but the links won't work still getting error 502 here is the link https://dashboard-app-production-55a9.up.railway.app/. What could be the problem and how can i get it resolved. In the picture you can see my custom start and build commands i'm using in railway.
