Expected Behavior

Just fail or error out on non-support node version so unhelpful error messages don't surface to users.

To Reproduce

Follow the steps to install turbopack quickstart:

Just to clarify @mehulkar the tool should in addition to having docs about its minimum supported node version, also fail if the minimum supported node version is not used.

Some of the example monorepos use tsup, which currently requires Node >= v18.

My project was failing completely to start with Turbopack using Node v16.

I was getting:

failed to convert header to a str

Debug info:
- Execution of resolve_source_request failed
- failed to convert header to a str

With v18.16.0 works fine.

Next.js requires Node.js 18 on the latest version so this issue is no longer relevant. Going to close it 🙏 Thanks for the report!
