NextJS 13.4 App Router: Undefined property error during AirTable API request

I’m having trouble with the new App router in NextJS 13.4. I’m trying to make an API call to AirTable, but I’m getting a weird error. The data comes through fine, but Next throws an error that messes up my try-catch block. Here’s what it says:

TypeError: Cannot read properties of undefined (reading 'headers')

My setup is pretty simple. I’ve got a client component in /app/dashboard/page.js that sends a GET request to /api/jobs. The API route handler is in /app/api/jobs/route.js. It talks to AirTable and should send back some data.

The funny thing is, if I comment out the AirTable API call, the error goes away. And if I move the whole AirTable thing to the client component, it works perfectly.

I’m stumped. Is there something about NextJS that I’m missing? Any ideas on how to fix this? I’ve been banging my head against the wall for hours now. Help would be awesome!

I encountered a similar issue when working with the new App Router. The problem might be related to how Next.js 13.4 handles API routes differently. Have you tried using the ‘NextResponse’ object instead of the standard ‘Response’? It’s designed specifically for Next.js API routes and might resolve your headers issue.

Here’s a quick example of how you could modify your route handler:

import { NextResponse } from 'next/server';

export async function GET() {
  try {
    const airtableData = await fetchFromAirtable();
    return NextResponse.json(airtableData);
  } catch (error) {
    console.error('AirTable fetch error:', error);
    return NextResponse.json({ error: 'Internal Server Error' }, { status: 500 });
  }
}

This approach has worked well for me in similar situations. Let me know if it helps!

I’ve been there, mate. The App Router can be a bit tricky at first. Have you checked your environment variables? Sometimes, the issue can be as simple as that. Make sure your AirTable API key is properly set in your .env.local file and that you’re accessing it correctly in your code.

Also, it might be worth looking into using SWR or React Query for data fetching. They handle a lot of the complex state management and error handling for you, which can be a lifesaver when dealing with API calls in Next.js.

If all else fails, you could try setting up a custom server using Express.js. It’s a bit more work, but it gives you more control over how requests are handled. Just remember to update your next.config.js file if you go down this route.

Keep at it, you’ll crack it soon enough!

hey man, i had a similar issue. try wrapping ur airTable API call in a try-catch block inside the route handler. also, make sure ur using the correct Next.js 13.4 syntax for API routes. somethin like:

export async function GET() {
  try {
    // AirTable API call here
  } catch (error) {
    console.error(error);
    return new Response('Error', { status: 500 });
  }
}

hope this helps!
