Google Apps脚本中的createFile（）无法正常运行

我正在尝试创建一个文件。当我从应用程序脚本中的调试器运行以下代码段时，它工作正常。但是，当我从电子表格实时运行它时，它说我没有调用createfile的权限。记录的所有内容都是相同的。问题不在于我没有权限，因为我是电子表格中的唯一人员并且是所有者。CSV的目的是将其从我的Google驱动器移至BigQuery的数据中

function saveAsCSV(row) { //Doc to Csv
//row = 3; //when this is uncommented and ran from the debugger, it works.

 try{

var fileName=  Date.now()
fileName = fileName + ".csv";


var csvFile = convertRangeToCsvFile_(fileName,row);
Logger.log(csvFile); //Both times ran on the spreadsheet and from debug equals the same.

DriveApp.createFile(fileName, csvFile);


SpreadsheetApp.getActiveSpreadsheet().getSheetByName("New and Open").getRange("J" + row.toString()).setValue("");

loadCsv(fileName);

}
catch(e){Logger.log("B" + e.message);} //No permission to create file
}



function convertRangeToCsvFile_(csvFileName, r) {

var ws = SpreadsheetApp.getActiveSpreadsheet();
try {
//var data = ws.getValues();
var csvFile = undefined;

var csv = "";
var row = r;

var datArray = Create2DArray(1,19);


  datArray[0][0] =  ws.getRange("A" + row.toString()).getValue().toString().toUpperCase();
  datArray[0][1] =  ws.getRange("B"+row.toString()).getValue().toString().toUpperCase();
  datArray[0][2] =  ws.getRange("C"+row.toString()).getValue().toString().toUpperCase();
  datArray[0][3] =  ws.getRange("D"+row.toString()).getValue().toString().toUpperCase();

  datArray[0][7] =  ws.getRange("H"+row.toString()).getValue().toString().toUpperCase();
  datArray[0][8] =  ws.getRange("I"+row.toString()).getValue().toString().toUpperCase();
  datArray[0][9] =  new Date(ws.getRange("K"+row.toString()).getValue().toString()).getHours();

  datArray[0][17] =  new Date(ws.getRange("N"+row.toString()).getValue().toString()).getMonth();
  datArray[0][18] =  new Date(ws.getRange("N"+row.toString()).getValue().toString()).getDate();

for(var i = 0; i < 19; i++){
  if(datArray[0][i] == ""){if(i > 9){datArray[0][i] = 0;} else{datArray[0][i] = "nil";} } 
  if(i < 18){csv += '"' + datArray[0][i] + '"' + ",";}
  else{ csv += '"' + datArray[0][i] + '"'; }
}

Logger.log("A " + csv);
Logger.log(csv + "\n" + datArray[0].join(","));
csvFile = csv;
return csvFile;
