錯誤：「無法發送電子郵件：無收件人」

Question

我得到的錯誤，當我運行下面的代碼：

Failed to send email: no recipient

這是正在流失或谷歌電子表格。我假設它將在電子郵件地址欄中查找電子郵件地址，並在它讀取最後一個電子郵件地址後，它將轉到下一個空白單元格，並且看不到任何內容，然後發出錯誤消息。

如果是這樣的話，我怎樣才能讓它停止查找電子郵件地址，當它到列中的最後一個？

的錯誤是在第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 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 ('Support Staff') 
    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); 



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

你應該numRows行使用getLastRow()功能 [Ref]將其設置爲1000
