Hi, I’m trying to upgrade to Next 16 and now run into “URLPattern is not a constructor” for my proxy.ts. Checking its value it’s undefined. I’m importing it from next/server.
Applying a polyfil in instrumentation works locally but not on Vercel. Any ideas what could be going wrong? Weirdly enough docs recommend using this and I see no (recent) issues about this.
