錯誤：“無法發送電子郵件：沒有收件人”

Question

運行以下代碼時出現錯誤：

無法發送電子郵件：沒有收件人

這是正在運行或谷歌電子表格。 我假設它將在電子郵件地址列中查找電子郵件地址，在它讀取最后一個地址后，它會查找下一個空白單元格，但什么也沒看到，然后給出錯誤。

如果是這種情況，我怎樣才能讓它在轉到列中的最后一個時停止查找電子郵件地址？

錯誤在第 18 行： MailApp.sendEmail(emailAddress, subject, message);

    var EMAIL_SENT = "EMAIL_SENT";

function sendEmails2() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheets = ss.getSheets();
  var startRow = 2;  
  var numRows = 1000;
  var sheet = ss.getSheetByName ('Administrators')
  var dataRange = sheet.getRange(startRow, 1, numRows, sheet.getLastColumn());
  var data = dataRange.getValues();
  for (var i = 0; i < data.length; ++i) {
    var row = data[i];
    var emailAddress = row[1]; 
    var message = row[28];       
    var emailSent = row[29]; 
    if (emailSent != EMAIL_SENT) {  
      var subject = "Tuition Reimbursement Status";
      MailApp.sendEmail(emailAddress, subject, message);
      sheet.getRange(startRow + i, 30).setValue(EMAIL_SENT);


     var sheet = ss.getSheetByName ('Teachers')
     var dataRange = sheet.getRange(startRow, 1, numRows, sheet.getLastColumn());
     var data = dataRange.getValues();
     for (var i = 0; i < data.length; ++i) {
     var row = data[i];
     var emailAddress = row[1]; 
     var message = row[28];

       var subject = "Tuition Reimbursement Status";
       MailApp.sendEmail(emailAddress, subject, message);
       sheet.getRange(startRow + i, 30).setValue(EMAIL_SENT);


     var sheet = ss.getSheetByName ('Support Staff')
     var dataRange = sheet.getRange(startRow, 1, numRows, sheet.getLastColumn());
     var data = dataRange.getValues();

       var subject = "Tuition Reimbursement Status";
       MailApp.sendEmail(emailAddress, subject, message);
       sheet.getRange(startRow + i, 30).setValue(EMAIL_SENT);



      SpreadsheetApp.flush();
      }
     }
    }
   }
  }
 }

Answer 1

您的 numRows 應使用getLastRow()函數[Ref]設置，而不是將其設置為 1000。

Answer 2

“發送郵件失敗：沒有收件人”的解決方法

if (emailSent != EMAIL_SENT && emailAddress!="") { // Prevents sending duplicates
