Node.js middleware does not work with webpack builds

[cshawaus]

While attempting some build testing between Turbopack and Webpack, I noticed that Node.js middleware produces a CJS error and crashes the Edge Function. This is all I got in the logs, but tracing may provide more information.

With Next.js 16 moving to Turbopack by default, this doesn't feel like a high priority, but it's worth a mention in case anyone else is running up against it.
