Next.js downloads from fonts.googleapis.com during build

[DiskCrasher]

Summary

One of my build environments blocks access to the Internet. Next.js attempts to download from fonts.googleapis.com during build when a font is imported from next/font/google. This results in a failed build since the URL cannot be accessed.

A workaround is to add the font files directly to my project but this is not ideal because they would need to be manually updated if/when revisions are made upstream. Next.js should not be secretly accessing the Internet during builds.

Next.js 14.2.5

Failed to fetch font "Inter".

Please check if the network is available.

Next.js documentation states that next/font is "built in" with no indication that it will be downloaded during build:

"From version 13.2 onward, next/font has been built into Next.js, making the @next/font package redundant. The @next/font package will be completely removed in Next.js 14."

Example

import { Inter } from "next/font/google";
