GmailThread.reply works only first time

[jhaamit6666]

Hi all,

I am trying to send email programmatically in Google AppScript using GmailThread.reply(), but it works only first time. From 2nd time it gives me

Exception: Service invoked too many times for one day: email

So I have to run the script manually every time, but this doesn't make sense. Instead of this, I can send the emails manually. Does anybody know why is this happening?

I have used GmailMessage.reply() and GmailApp.sendEmail() also, but same error.

Thanks & regards,
