크롬 Inspector > Network > Preview,Response json확인하려면 res.json()실행되어야 함 (완전 몰랐던 사실)

return fetch(`${API_BASE_URL}/admin/terms/published-terms?type=${data}`, {
  method: 'POST',
  headers: getHeaders(),
})
  //.then(res => res.json())
  .then(body => {
    console.log('body', body);
    console.log('body json', body.json());//이게 없으면 크롬인스텍서 preview, response에서 안보임
    console.log('body body', body.body);
    if (body.status===200)
      alert('Successfully Published !');
    else
      alert('Some Error Occured !');
  })
  .catch(() => {});
