Error: Dynamic server usage

[markedwards]

This is somewhat related to #167, in the sense that this can be alleviated by specifying export const dynamic = "force-dynamic"; in next-rest-framework route handlers.

It looks like there's some call-stack issue where request.headers and request.url usage is generating Next build-time errors.
