Nextjs package breaks with turbopack

[sonyatalona]

hey team, noticed an interesting behaviour around nextjs, turbopack build, and @rivetkit/next-js (v 2.0.25) (yes, a weird connection).

I think what happens is that tsup bundles test files and some of the test packages/helpers are not very well supported by turbopack, thus it breaks. Resolution is to swap you build script to be like

"build": "next build --webpack",

however, it's a very top level patch that might not be an option for you.

Error: Turbopack build failed with 40 errors:
./node_modules/.pnpm/thread-stream@3.1.0/node_modules/thread-stream/test/ts.test.ts
Missing module type
The module type effect must be applied before adding Ecmascript transforms
