How to build without next export (using getStaticPaths fallback: true)

[tomsoderlund]

build is defined as "build": "next build && next export -o build" but it gives me the following build error:

Pages with `fallback` enabled in `getStaticPaths` can not be exported.
See more info here: https://err.sh/next.js/ssg-fallback-true-export

In a Next.js/React project I would just have:

"build": "next build"

but that gives this build error with Preact on Vercel:

Error: No Output Directory named "build" found after the Build completed.
You can configure the Output Directory in your Project Settings.

This sounds like the output directory is misconfigured in the project settings on vercel.
