How to handle error 405 POST req in API route?

Question

I want to display error response, i triedimport { NextRequest, NextResponse } from 'next/server';

export async function POST(req: NextRequest, res: NextResponse) {
  if (res.status === 405) {
    return NextResponse.json({
      // some json message
    });
  }
  try {
   // return data
  } catch (error) {
    return NextResponse.json({
      // some json message
    });
  }
}But it returns empty response, just http header 405

import { NextRequest, NextResponse } from 'next/server';

export async function POST(req: NextRequest) {
  try {
   // return data
  } catch (error) {
    return NextResponse.json({
      // some json message

  }
}

export function GET() {
  return NextResponse.json({ message: "method not allowed" }, { status: 405 })
}
