Mailapp.sendemail Failed

I have a script to automatically send an email. Unfortunately the script suddenly stopped working. I have changed nothing within the code. Can you help me? script: function SendEm

Solution 1:

You can try disabling Chrome V8 by going to the menu:

Run > Disable new Apps Script Runtime powered by Chrome V8.

This fixed the issue for me.

Solution 2:

For some reason, the email address is a type number. Coerce it to a string by using .toString()

MailApp.sendEmail(
  address.toString()
  subject,
  "Esteemed,\n\nAttached is the "+subject,
  {
    attachments: [file.getAs(MimeType.PDF)]
  }
)
