I cant figure out why google appscript is sending the actual file instead of the copy

Question

So, I recently have been working on a project with google sheets, where I am getting some data and creating files with that data to email as attachment. I am

• copying my template file
• setting a name to that template copy file
• opening it with the new copy id
• doing my replacements of tags (changing values of the copy template file)
• sending it as an email

    function sendEmail(){
        for (var row in rangeData) {
          var varify = false;
          var fileName = new Date().toString();
          Logger.log("template " + templateId);
          var fileId = DriveApp.getFileById(templateId).makeCopy().getId();
          DriveApp.getFileById(fileId).setName(fileName);
          var body = DocumentApp.openById(fileId).getBody();
          Logger.log('current row ' + rangeData[row]);
          for (var column in rangeData[row]) {
            var target = firstRowMapped.indexOf(columnNames[column]);
            if (target != -1) {
              Logger.log('found Key');
              try {
                body.replaceText(firstRowMapped[target].toString(), rangeData[row] 
                [target].toString());
                varify = true;
              } catch (err) {
                Logger.log(err);
              }
            }
          }
          if (varify == true) {
            var toSend = DocumentApp.openById(fileId);
            // send mail
            try {
              MailApp.sendEmail(rangeData[row][emailColumn], 'Test Email', rangeData[row][0], {
                name: 'Emailer Script from DOER',
                cc: rangeData[row][ccColumn],
                attachments: toSend.getAs(MimeType.PDF)
              });
              Logger.log('sent');
            } catch (err) {
              Logger.log(err);
            } 
          }
        }
      }

I am getting my expected files on google drive. The Id of those files match that of toSend yet when I am getting my email, I get the fileId. I have been trying to figure this out for days, no luck. Does anyone know why this might be happening? Any Ideas? I personally have send countless attachments through this process (not with a template though) and never had this problem.

Answer 1

The code in the question is opening two instances of the file, modifying one, then sending the other (unmodified) instance. To fix this, you can either:

Save and close the first instance before opening the other

/* globals
   rangeData, templateId, firstRowMapped,columnNames, emailColumn, ccColumn */

function sendEmail() {

    ...

    var doc = DocumentApp.openById(fileId);
    var body = doc.getBody();

    ...

    doc.saveAndClose();

    if (varify == true) {
      var toSend = DocumentApp.openById(fileId);
      // send mail
      ...

}

Or, only open one instance, and send the same one you modified

// Don't close the doc before this 
var toSend = doc;
