Make sure the directory is api

I have done this, it didn't work, can I chat you privately

No, Can you send the error which you get

OK in my application, locally I run my TypeScript index.ts which is in src but on production I compiled the TypeScript into api folder with index.js as the entry file. So when I want to deploy to vercel, how do I set up my build command because I have a start script that runs the compiled index.js

You can set compile command as build command in Vercel

I will show you the error once I put on my pc,

I have a route '/' which displays a html message showing my API is working

But it is not showing up here

Can you share additional details
