Hi,

You are most likely reaching for API Routes, or Handlers (in App Router), during build time. That won't work because there's no server to take care of them while building the app.

You also most likely have wrapped a try/catch block around the fetch requests, which is very nice, and something most people forget to do.

That being said, when you run your app, you probably will not see what you expect. Not sure what kind of pages you have, pre-rendered or on-demand.

To fix this, please refer to this:
