This pull request is a temporary addition that uses the
x-now-route-params
header in serverless.This header returns the regex groups with indexes, not their named variants.
As a result, we must use the
getRouteMatcher
utility to reverse this into Next.js' expected names.Since this got complex, I've added a test for it. We should probably remove this behavior sooner than later.
