I have a NextJS API router handler that uses tRPC and searchParams to accept external request to the web app.

Here is what I started with:

import type { NextRequest, NextResponse } from 'next/server';
import { api } from '@/trpc/server';

export const GET = async (req: NextRequest, _res: NextResponse) => {
  try {
    const { searchParams } = new URL(req.url);
    const startDate = searchParams.get('start');
    const endDate = searchParams.get('end');

    if (!startDate || !endDate) {
      throw new Error('Start and end time are required');
    }

    const coords = await api.nmea.getExpeditionPath.query({
      order: 'DESC',
      start: startDate ?? '',
      end: endDate ?? '',
      intervalSeconds: 3600 * 4,
    });

    return new Response(JSON.stringify(coords));
  } catch (e) {
    console.error(e);
    return new Response(e instanceof Error ? e.message : 'Server Error');
  }
};

After reading the docs I ended up with this:

import type { NextRequest, NextResponse } from 'next/server';
import { api } from '@/trpc/server';

export const dynamic = 'force-dynamic';

export const GET = async (req: NextRequest, _res: NextResponse) => {
  try {
    const searchParams = req.nextUrl.searchParams;
    const startDate = searchParams.get('start');
    const endDate = searchParams.get('end');

    if (!startDate || !endDate) {
      throw new Error('Start and end time are required');
    }

    const coords = await api.nmea.getExpeditionPath.query({
      order: 'DESC',
      start: startDate ?? '',
      end: endDate ?? '',
      intervalSeconds: 360,
    });

    return new Response(JSON.stringify(coords));
  } catch (e) {
    console.error(e);
    return new Response(e instanceof Error ? e.message : 'Server Error');
  }
};

The updates resolved the error when building and running the app in production mode locally but I am still getting these errors on Vercel.
