accessToken의 기한이 완료되면, updateToken을 하는데 그때 "Fail to find provider"가 발생함.

해당 오류에 대한 분석 결과와 수정 내용입니다.

try {
    var items = body.items;
    log.debug("items length=" + items.length, meta);

구글의 blogger에서 블로그가 없을 경우 body.items 가 undefined 입니다. undefined.length에서 exception이 발생했습니다.

아래와 같이 수정할 예정입니다.

if(body.items !== undefined) {
    try {
        var items = body.items;
        log.debug("items length=" + items.length, meta);
