Hi !
I'm currently building a PWA application (@ducanh2912/next-pwa)
When I build locally I don't have error. (PWA is disabled locally) but when I push, I have an error on Vercel:

TypeError [ERR_INVALID_ARG_TYPE]: The first argument must be of type string or an instance of Buffer, ArrayBuffer, or Array or an Array-like Object. Received undefined

It seems that Vercel try to access my route during the build phase ?

Here is my api route code:

import { NextResponse, NextRequest } from "next/server";
import PubSub from "@/lib/pubsub";

export async function POST(req: NextRequest, res: NextResponse) {
  const body = await req.json();
  const { topic, subscription } = body;

  if (!topic || !subscription) {
    return Response.error();
  }

  await PubSub.createSubscription(topic, subscription);

  return Response.json({ success: false, message: "Subscription created" });
}

Any ideas ? many thanks !
