Got stuck most of the day on an automation.
The task: for a private chef service, generate a clean-looking PDF with each new form submission and push it back into an n8n workflow. There weren’t any built-in HTML to PDF options (outside paid tools or self-hosting n8n and using an opensource app installed), So with power of AI I coded my own small API that takes HTML, renders a PDF, and returns it to n8n. Deployed it on Vercel so the client can use it for free. The annoying bit: CSS wouldn’t load in the PDF for more than 3 hours plus. No clear reason, but I worked around it and now have a working solution. I used Claude Code to create the API. Hosted on Vercel for free Google Drive to upload the PDF to n8n for the automation
