Hello everyone,

I'm encountering an issue with redirection using a Next.js API route. I have a router.ts file located at /api/auth/sign-in with a simple logic as follows:

export async function POST(request: Request) {
  const requestUrl = new URL(request.url);

  return NextResponse.redirect(
    `${requestUrl.origin}/auth/register`,
    {
      status: 301
    }
  );
}

When I make a POST request using the following code:

export const handleSignIn = async(data : ILoginForm) => {
  await fetch('/api/auth/sign-in', {
    method: 'POST',
    body: JSON.stringify(data)
  });
};

The POST request works correctly, but the redirection doesn't happen. In the network tab, I can see the information shown in the attached image.

Does anyone have insights into what might be causing this issue? Any help or suggestions would be greatly appreciated.
