In API Route Handlers, HTTP method functions should adhere to the syntax:
export async function METHOD() {}

export async function POST(req: NextApiRequest, res: NextApiResponse) {
// Your existing POST request handler code
}
Ensure that corresponding HTTP methods (e.g., GET, PUT) are similarly defined as named exports in the API Route Handler file.
