nextjs 13.4 app router , APIs endpoint POST , can't json() "parse" the request to access the body

Question

export async function POST(req:Request) {
  
  try {
    const body = await req.json()
    console.log(body);
    return new Response("ok")
  } catch (error) {
    console.log(error);
  }

}

when using postman to send a payload , the server console spits an 500 internal server error and this code will spit this :

SyntaxError: Unexpected number in JSON at position 1
    at JSON.parse (<anonymous>)
    at parseJSONFromBytes (node:internal/deps/undici/undici:6498:19)
    at successSteps (node:internal/deps/undici/undici:6472:27)
    at node:internal/deps/undici/undici:1145:60

    at AsyncResource.runMicrotask (node:internal/process/task_queues:137:8)
    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)

EDIT : the endpoint i'm trying to reach is in app/api/testPost/route.tsx Postman ScreenShot : screenShot

Can you show the data you are sending from postman, and also a screenshot? This more likely due to a non correctly formatted data. — Youssouf Oumar, May 10 '23 at 20:50
In postman, chose raw and then JSON if want to parse the body as JSON. — Youssouf Oumar, May 11 '23 at 10:20

Comment out output: 'export' in next.config.js file and try again.
