URL_PERFORMANCE_REPORT not all urls listed

[Mihail Ma]

Hi!

I have VideoAd, and when i see dispayed urls in Web Interface of AdWords - there are above 4000 youtube channels, but when I get it from URL_PERFORMANCE_REPORT by script - there only 183 URLs. Why??

My script:
var period = '20180625, 20180625';
function main() {
 var videoIdList = [];


  var report = AdWordsApp.report(
     'SELECT CampaignName, Url, AdGroupName ' +
    'FROM  URL_PERFORMANCE_REPORT ' +
    'WHERE CampaignId = 1177713739 ' +
  //   'AND AdNetworkType1 IN [YOUTUBE_SEARCH, YOUTUBE_WATCH] ' +
    'DURING ' + period, { includeZeroImpressions : true });


  var rows = report.rows();


  while (rows.hasNext()) {
    var row = rows.next();
    var videoId = row['Url'];
    videoIdList.push(videoId);
  Logger.log(row['CampaignName'] + " - " + row['AdGroupName'] + " - " + row['Url']);
   }
Logger.log("Total Rows - " + videoIdList.length);
}
