Creating a YouTube Video or Channel ID validation in Apps Script

问题

I am learning how to use the YouTube Data API through Apps Script. I am now trying to modify the example provided here https://developers.google.com/youtube/v3/quickstart/apps-script to verify if the ID exists.

I slightly modified it to look at video IDs since that is more common.

With help by @Tanaike based on my last question, Tanaike helped me create a loop to allow the script to add IDs as comma-separated. Now I'm trying to add a validation.

function channelsListByVideoid(part,params){
  var response = YouTube.Videos.list(part,params);
  var video = response.items[0];
  var dataRow = [video.id,video.status.uploadStatus, video.snippet.title, response.pageInfo.totalResults, video.snippet.channelId, video.snippet.channelTitle];
  SpreadsheetApp.getActiveSheet();
  SpreadsheetApp.getActiveSpreadsheet().getSheetByName().appendRow(dataRow);

function getvideo() {
  var ui = SpreadsheetApp.getUi();
  var videoId = ui.prompt("Enter the YouTube Video ID: ").getResponseText();
  var values = videoId.split(",");
for (var i = 0; i < values.length; i++) {
  channelsListByVideoid('snippet,status,contentDetails,statistics', {'id': values[i].trim()});

Sometimes, a video ID such as https://www.youtube.com/watch?v=--fPZOu_H8g is not available. Running that ID within the apps-script example will throw an error TypeError: Cannot read property 'id' of undefined which will stop the script from running.

I was thinking about how to use video.list.response Property:

{
  "kind": "youtube#videoListResponse",
  "etag": etag,
  "nextPageToken": string,
  "prevPageToken": string,
  "pageInfo": {
    "totalResults": integer,
    "resultsPerPage": integer
  },
  "items": [
    video Resource
  ]
}

The totalResults and the resultsPerPage will show as 1 if the video is valid and 0 if invalid:

"pageInfo": {
  "totalResults": 0,
  "resultsPerPage": 0

which can be verified through the API explorer (https://developers.google.com/youtube/v3/docs/videos/list?apix_params=%7B%22part%22%3A%22snippet%2CcontentDetails%2Cstatistics%22%2C%22id%22%3A%22--fPZOu_H8g%22%7D)

I added ```` response.pageInfo.totalResults,


Logically to me, I need to add a 
````var response```` 
to my getvideo() and add the validation check within the loop.

I'm not clear if you can write it as simply as

if response.pageinfo.totalResults = 1 then "valid" ELSE "Invalid"

and then how to allow the code to skip the error that is generated.

Thank you!
