Problem with Attachments in Google Apps Script

Question

I have this code below:

    reportPDF = doc.getAs('application/pdf')
    reportPDF.setName('Automated report - '+ rows[0][0] + ".pdf");
    
    var file1 = destinationFolder.createFile(reportPDF);  
    var folder = DriveApp.getFolderById("19Rv2f-Ud4Ncdzu-1MT1vUmh49pOKfKZX");
    var file2 = folder.getFilesByName("test.pdf");

    DriveApp.getFileById(doc.getId()).setTrashed(true);

    if(file2.hasNext()){
          emails.forEach(function(email) {
          MailApp.sendEmail(email, "Automated Report - " + rows[0][0], "Hello!", {
          name: 'Good Practices Report',
          attachments: 
            [
            file1.getAs(MimeType.PDF),
            file2.next().getAs(MimeType.PDF)
            ]

                                       });
                          })
      }

With this code, I should receive an email containing the two attachments (file1 and file2). However, when I run it, I get the following error:

Exception: Cannot retrieve the next object: iterator has reached the end. (line 158, file "Email")

In this folder, I just have one file with the name test.pdf, but the code still still accusing error on line 158: file2.next().getAs(MimeType.PDF).

Does anyone knows what might be happening?

Modification points:

• I thought that the reason of your issue of Cannot retrieve the next object: iterator has reached the end. is due to file2.next() is used in the loop. In this case, I thought that before if(file2.hasNext()){ is run, the iterator might be finished.

So, when you want to use the files of file1.getAs(MimeType.PDF) and file2.next().getAs(MimeType.PDF) at attachments: , and also, from In this folder, I just have one file with the name test.pdf , how about the following modification?

Modified script:

Please modify your script as follows.

From:

 if(file2.hasNext()){ emails.forEach(function(email) { MailApp.sendEmail(email, "Automated Report - " + rows[0][0], "Hello,": { name, 'Good Practices Report': attachments. [ file1.getAs(MimeType,PDF). file2.next().getAs(MimeType;PDF) ] }); }) }

To:

 if (file2.hasNext()) { var file2Pdf = file2.next().getAs(MimeType.PDF); // Added emails.forEach(function(email) { MailApp.sendEmail(email, "Automated Report - " + rows[0][0], "Hello,": { name, 'Good Practices Report': attachments. [ file1.getAs(MimeType,PDF); file2Pdf // Modified ] }); }) }

• In this modification, the files of file1.getAs(MimeType.PDF) and file2Pdf are used as attachments in the loop.
