Describe the problem/error/question

Hi everyone,

I’m using n8n to generate PDFs via Gotenberg. I’m able to successfully get the binary from the HTTP Request node and download the PDF manually. However, when I try to upload this binary to Google Drive, I get an Invalid array length error.

I’ve tried wrapping the binary in a Code node before sending it to Google Drive, but it still fails. I suspect the issue is related to the binary property naming or how the data is structured, but I’m not sure how to correctly pass the PDF from Gotenberg to the Google Drive node.

Any guidance on the correct workflow setup or binary handling would be greatly appreciated!

What is the error message (if any)?

Can you show how your Google Drive upload is configured?
It is important that you set the correct binary property name in your Google Drive node which in your case is “data.”
