## Summary
- Fixes the `createRequest` call in `renderToPipeableStream` to pass
`debugChannelReadable !== undefined` instead of `debugChannel !==
undefined` in the turbopack, esm, and parcel Node.js server
implementations
- The webpack version already had the correct check; this brings the
other bundler implementations in line
The bug was introduced in #33754. With `debugChannel !== undefined`, the
server could signal that debug info should be emitted even when only a
write-only debug channel is provided (no readable side), potentially
causing the client to block forever waiting for debug data that never
arrives.
