Not working with Next.js 16 and turborepo

[tuke307]

Problem

The build pack turborepo is the standard for Next.js 16 now. When executing next dev it uses turborepo automatically.

use the Next js integration example and update to the newest packages with e.g. ncu -u or by manually updating.

with standard (turborepo):

~/source/project % npx next dev
   ▲ Next.js 16.0.1 (Turbopack)
   - Local:        http://localhost:3000
   - Network:      http://xxx:3000
   - Environments: .env

 ✓ Starting...
Error: loader /.../node_modules/@next/mdx/mdx-js-loader.js for match "{*,next-mdx-rule}" does not have serializable options. Ensure that options passed are plain JavaScript objects and values.
    at ignore-listed frames

Workaround

As a workaround, use webpack for building.
with webpack:

~/source/project % npx next dev --webpack
   ▲ Next.js 16.0.1 (webpack)
   - Local:        http://localhost:3000
   - Network:      http://xxx:3000
   - Environments: .env
