例外：无法发送电子邮件：没有收件人

Question

Honestly I'm lost. I'm trying to send email responses from a spreadsheet, found this script, edited it a bit and now it won't send emails. This goes beyond my knowledge so now I'm here. Someone please help me out.

// add menu to Sheet
function onOpen() {
  var ui = SpreadsheetApp.getUi();
  
  ui.createMenu("Send Emails")
  .addItem("Send Email Batch","createEmail")
  .addToUi();
}

/**
 * take the range of data in sheet
 * use it to build an HTML email body
 */
function createEmail() {
  var thisWorkbook = SpreadsheetApp.getActiveSpreadsheet();
  var thisSheet = thisWorkbook.getSheetByName('Formulierreacties 1');
  var startRow = 2;  
  var numRows = thisSheet.getLastRow();

  // get the data range of the sheet
  var allRange = thisSheet.getRange(startRow, 1, numRows, thisSheet.getLastColumn());
  
  // get all the data in this range
  var allData = allRange.getValues();
  
  // get the header row
  var headers = allData.shift();
  
  // create header index map
  var headerIndexes = indexifyHeaders(headers);
  
  allData.forEach(function(row,i) {
    if (!row[headerIndexes["Status"]]) {
      var   htmlBody = 
        `Hi,

          Thanks for filling in the warning appeal!

            Your answers:

              What is your user ID?
              ${row[headerIndexes["What is your user ID?"]]}

              What was the case ID of your warning?
              ${row[headerIndexes["What was the case ID of your warning?"]]}

              What was the reason for your warning?
              ${row[headerIndexes["What was the reason for your warning?"]]}

              How many points were you warned for?
              ${row[headerIndexes["How many points were you warned for?"]]}

              Did this warning lead to you being banned from the server?
              ${row[headerIndexes["Did this warning lead to you being banned from the server?"]]}

              Why do you think this warning should be lifted?
              ${row[headerIndexes["Why do you think this warning should be lifted?"]]}

                Reply:

                ${row[headerIndexes["Custom Reply"]]} 
 
                  Have a great day.

There's probs a lot wrong with this, but I just don't see it. I'm gonna look into it more, but I hope the wonderful smart developers of (Heaven) stackoverflow could see the issue and resolve it for me. I normally don't ask to be spoon feed, but I have been staring at this for about 2 hours, got a headache, and officially lost and feeling like a complete and utter idiot.

Answer 1

Instead pushing lines and lines of code and realize at the end of the week that nothing work, start to code step by step. Just try to make this line working:

GmailApp.sendEmail( "put your email here", 'this is a test', "and it work");

If it doesn't work, maybe:

• GmailApp is not initialized, so the mail is not send
• you see no mail cause they goes into spam, try to send them to a mailer without any spam system.

If it works, change you call, you're content is no html, maybe this is the mistake

GmailApp.sendEmail(
    recipient,
    "Thanks for filling in the warning appeal!", 
    body
  );

If it is no working, add the following line just before:

console.log('Sending email to', recipient);

And check recipient is correct.
