Hello!
I've some problems using this lib with next 13 using app router. The usage mode described in README.md, doesn't work properly. I tried use as API Route and Route Handler but don't work as well.

Examples:

API routes

In this way i receive 404 page.

Route Handlers

In this way i receive this error:

auth host=undefined
- error TypeError: res.writeHead is not a function

I'm not sure if is correct pass NextResponse

What I'm doing wrong?

Thanks.
