What is your goal?
Send an individual pdf to a specific person based on my Google Sheet data mapping
Add the personalized attachment PDF from Google Drive to Gmail
What is the problem?
The email is send properly (content) and a pdf attachment is added but the doc is empty (only 1kb)
What have you tried so far?
I changed the mapping several time, add an array in between the file download and gmail.
Change the mapping in the gmail attachement data field to try to find the right one.
Try to run only the google drive - download a file section but got the error: [403] Export only supports Docs Editors files.
