[Turbopack Nextjs 16]: Pino - Cannot find module './transport-stream'

This is the same issue as #86099. The original issue deviated to Turbopack + non-Vercel deployment and closed after that case was fixed. However, the Turbopack + Vercel deployment (AWS Lambda) scenario still has the errors below, tested with v16.1.0.

Thanks @lukesandberg for the workaround https://github.com/CHC383/nextjs-turbopack-pino-reproduction/pull/1

To Reproduce

1. Deploy the code to Vercel
2. Visit /api/log
3. Check the log of the Vercel deployment

Current vs. Expected behavior

Current behavior

With Turbopack in NextJs v16, Pino worker thread throws the following error:

Uncaught Exception: Error: Cannot find module './transport-stream'

Expected behavior

Pino worker thread works without any exception, which is the behavior of using WebPack.

Additional context

No response

Start with the linked nextjs-turbopack-pino-reproduction repository and reproduce the failure by deploying to Vercel, visiting /api/log, and checking the deployment log. Then inspect the Pino worker entry point at node_modules/pino/lib/worker.js and compare the Turbopack deployment with the stated Webpack behavior. Done means the Pino worker runs on the Vercel AWS Lambda deployment without the missing-module exception.
