I'm running a worker locally whose work is to return the request.body back, and  I made a POST request with some body in application/json format, but in response I get {}, but request.cf is working perfectly, and on request.bodyUsed, I get false

export default {
  async fetch(request, env, ctx) {
    const { pathname } = new URL(request.url);
    if (pathname === "/api/modify") {
      return Response.json(request.body);
    }
  }
}

.body is a ReadableStream that can’t be stringified

If it’s valid JSON, do await request.json() to get an object representing it
