Apps script: Missing rows in output

I'm learning how to query the YouTube API with apps script by following this tutorial.

Using the tutorial, I've built the below code. The issue that I have is that for some of the search queries in my arrSearchItems array, some rows get skipped when outputting to Google Sheets.

function myFunction() {
  var ss = SpreadsheetApp.openById(<spreadsheet_ID>);
  var activeSheet = ss.getSheetByName("YouTube Results");

  let executionTime = Utilities.formatDate(new Date(), "GMT+1", "yyyy/MM/dd HH:mm:ss");

  var arrSearchItems = ["attack on titan", "mob psycho 100", "demon slayer", "vinland saga", "goodnight punpun"];

  activeSheet.getRange("A2:H").clearContent();

  for (let i=0; i < arrSearchItems.length; i++) {

    let search = arrSearchItems[i]
    Logger.log((i+1) + ') ' + search);

    var sr = YouTube.Search.list("snippet,id", { q : search, maxResults : 50, order : "viewCount"});
    var srVidsOnly = sr.items.filter( function (res) { return res.id.kind === "youtube#video"} );

    var modRes = srVidsOnly.map( function (v) { return [v.id.videoId, v.snippet.title, v.snippet.publishedAt]; } );

    var ids = modRes.map( function (res) { return res[0]; } ).join(",");

    for (let j=0; j < modRes.length; j++) {
      modRes[j].unshift(search.toUpperCase()); // add the search query to the front of the array
    }

    for (let k=0; k < modRes.length; k++) {
      modRes[k][1] = "https://www.youtube.com/watch?v=" + modRes[k][1]; // update the video ID to a video link
    }

    var stats = YouTube.Videos.list("statistics", {id : ids});

    var vidsStats = stats.items.map ( function (res) { return [res.statistics.viewCount, res.statistics.likeCount, executionTime] } );

    var rowStart = (i*50) + 2 // row start for the next search query when outputting to GSheets

    activeSheet.getRange(rowStart, 1, modRes.length, modRes[0].length).setValues(modRes);
    activeSheet.getRange(rowStart, 5, vidsStats.length, vidsStats[0].length).setValues(vidsStats);

    Logger.log('row start = ' + ((i*50)+2))
    Logger.log(modRes)
    Logger.log(vidsStats)

  }

  //Logger.log(sr.items)
  
}

For example, in the image rows 198 - 201 have missing values when they should be populated.

I'm not sure why this is happening. Any ideas?
