What is your goal?
I’m facing an issue in Make.com with Gmail attachments and embedded images.
Workflow summary:
A strategic report is generated successfully as a PDF
The PDF is downloaded/exported correctly from Google Drive
The PDF is then analyzed by AI to generate a custom outreach email
Gmail module then sends:
custom email body
one embedded PNG image/signature
one attached PDF report
recipient email from Google Sheets
What is the problem & what have you tried?
Issue:
Gmail keeps throwing:
“File name: Value must not be empty”
“Data: Value must not be empty”
Important details:
PDF export/download is working correctly
PNG image download is also working correctly
PDF binary starts with %PDF
PNG binary starts with 89 50 4E 47
I tested using:
only PNG
only PDF
both together
Same error appears in all cases
Tried static filename values as well
Gmail body type selected:
“Text, files and images”
not raw HTML
The issue seems to happen specifically when downloaded binary files are passed into Gmail as:
embedded image
attachment
