fs.writeFile(fname,text); 부분에서 오류가 나길래 공식 문서를 찾아보니

fs.writeFile(file, data[, options], callback)
https://nodejs.org/dist/latest-v10.x/docs/api/fs.html#fs_fs_writefile_file_data_options_callback

함수의 인자로 3개를 받고 마지막에 콜백함수를 받는다고 합니다.

예제코드를 아래와 같이 바꾸니 해결됬습니다.
fs.writeFile(fname, text,(err)=>{
if (err) throw err;
});
