New to Node and having trouble with the Youtube Data API - node.js

Question

Using Node.js for the first time and working with the Youtube Data API. I can't quite get the data I want from the API when I make a request to it. This is what the data coming back from the API is supposed to look like:
/**
* API response
*/
{
"kind": "youtube#commentThreadListResponse",
"etag": "\"VPWTmrH7dFmi4s1RqrK4tLejnRI/yVL3QyyDwJFkFNOcCd4KZCcTFDw\"",
"nextPageToken": "QURTSl9pMlQySG1zcHRKb0dNZ3dWdlYtcUhyRDFDVlJXaHFmdVFiMUlaUFJfTTNjdTFpQzFNWUNuWjhBY0d2ZV8tTGR2aHFXRXRJVDZRQVpRM0YzNndWVXlQVFNwOU94UVFCWVd2empIVUlGdHlFR25keU8=",
"pageInfo": {
"totalResults": 20,
"resultsPerPage": 20
},
"items": [
{
"kind": "youtube#commentThread",
"etag": "\"VPWTmrH7dFmi4s1RqrK4tLejnRI/OqxtT8nFAjcFFrHa4DbZrY_NItM\"",
"id": "z13bwzmokuzcxtcqn04cclqbiozixldh21o"
},
{
"kind": "youtube#commentThread",
"etag": "\"VPWTmrH7dFmi4s1RqrK4tLejnRI/1B_usKd_ZpCLxG5l5nL7QfUtG3o\"",
"id": "z13puhijunbzytdcn22lstwptmybyzwdl"
},
{
"kind": "youtube#commentThread",
"etag": "\"VPWTmrH7dFmi4s1RqrK4tLejnRI/h8sS5KTOFa7CQWU5Je2Fp5UQ0bk\"",
"id": "z13dfbwzjyrpiznqc04cgjlpbyn0wtaiqpw0k"
},
{
"kind": "youtube#commentThread",
"etag": "\"VPWTmrH7dFmi4s1RqrK4tLejnRI/FQEl6XU95FHiM1ijRxC5fqngmqk\"",
"id": "z12atro51wfhzvmp104cihfytveyshbr4s40k"
},
{ ...........AND SO ON
I then use the following code in an attempt to console.log() this data from the youtube API
var DATABASE = youtube.commentThreads.list(
{ 'videoId': '7YcW25PHnAA', 'part': 'id, replies'}, function(err, data){
if(err){
console.error('Error: ' + err);
}
});
var resp = JSON.stringify(DATABASE);
console.log(resp);
But this is my output instead:
