Request from Next.js 13 (as front-end) to Hono server doesn't work

[GutoFrr]

In my Hono server with Node.js I have this controller to a get method. The path to it is 'http://localhost:5000/api/products'

async function getProducts(c: Context) {
  const products = await prisma.product.findMany({
    select: {
      ...PRODUCT_FIELDS,
      user: {
        select: {
          name: true,
        },
      },
    },
  });
  if (products.length === 0) {
    return c.json({ message: 'Não há produtos cadastrados...' }, 404);
  }

  return c.json({ products }, 200);
}

The Next.js data fetching function is this one:

async function getProducts() {
  try {
    const res = await fetch('http://localhost:5000/api/products', {
      cache: 'no-store',
    });

    const data = await res.json();
    console.log(data);

    return data.products as IProduct[];
  } catch (error) {
    console.log(error);
  }
}

The error is this:
TypeError: fetch failed
at Object.fetch (node:internal/deps/undici/undici:11413:11)
at process.processTicksAndRejections (node:internal/process/task_queues:95:5) {
cause: Error: connect ECONNREFUSED ::1:5000
at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1494:16)

errno: -4078,
code: 'ECONNREFUSED',
syscall: 'connect',
address: '::1',
port: 5000
}
}

In Next.js, I can fetch the data successfully as a client function (useState and useEffect), but I can't with a server-side request, as it is described above. The request route doesn't require authentication, any user should be able to fetch the data.

Is important to remind that my Next.js front-end is not connected with Hono RPC. The server (Hono) and the client (Next.js) are in separate folders.

Well, my question here is how to connect an outside client to a Hono server. Thanks for helping!

I hope this can be fixed...

I fixed it... It was a silly issue. I did not know I needed to define the hostname in the serve function.
