Regarding HTTP Request / Get File Node

Issue when downloading a PDF with HTTP Request

Hey @Philip_Wiggins When we create binary data now, we store additional metadata like file-name, file-size, mime-type, etc. After that when you change the filename in the code node, you are changing the value in an in-memory copy of this data. If you use this binary data in another node (i.e. to upload the file somewhere) later in the workflow, the updated file-name will be used, but the download currently will use the filename that’s in the metadata when the binary data was created. If you …

Hi Netroy, in this post above I think you give the answer to the problem I’m facing. I would like to ask you if you could change the behavior of the n8n-node as you said there in the last sentence: “If you feel that this behavior is incorrect, then we can add the file-name in the download URL, and then use that file-name for the downloaded file instead.”

I try to download a PDF file from an Airtable attachment field and send it via an SMTP-Node as email attachment. The email arrives with the correct file attached, but that file doesn’t have a .pdf ending. Non-tech-savvy recipients then can’t open it.

My n8n version is 1.42.1

What do you think?

It looks like your topic is missing some important information. Could you provide the following if applicable.

• n8n version:
• Database (default: SQLite):
• n8n EXECUTIONS_PROCESS setting (default: own, main):
• Running n8n via (Docker, npm, n8n cloud, desktop app):
• Operating system:

Hi @masesi ,

Welcome to the community!

Would you be able to share your workflow to see how you’re passing the data?

I tried to reproduce the error but my file keeps returning with the .pdf termination

I figured it out! The problem was that I’m using another workflow to create that pdf-document in the first place (by merging 2 other pdf files) and then name that new pdf file with a variable filename from another formula field. In that formula I simply added “.pdf” at the end and voila, it works! I just never saw that the file stored in Airtable has no file ending as the Finder on Mac automatically adds .pdf to the filename when downloading it manually from Airtable.
