Fixing PDF Extensions When Uploading Invoices to S3

·Apr 09, 2025 12:35 PM·

Hey! Been trying to grab invoices from my emails and upload them to S3. However, whenever they get to S3, the PDFs have a “undefined” extension. More details in comments

hey there! I just double-checked and it seems to work on my end. Can you try to set the type to application/pdf ? also, in my test the auto file name field added another .pdf extension so might be worth prompting the field to avoid .pdf.pdf 🙂

Weird, this system still creates .undefined files when uploaded 😕 did you have a specific s3 setup ?

Hmm no. But I can see from the new task of yours today it seems to work?! → just the .pdf.pdf issue seems to remain

yep, it seems to have added the correct value now (just double pdf extension), however the output file “Object URL” in S3 shows an XML error and it shows a 0 B total size
