I am a beginner in n8n and I am setting up a workflow for our finance team that is intended to download invoice attachments such as PDF and CSV files from our supplier's portal. The flow runs until the most important node, namely the login procedure, is executed, at which point I keep getting a 401 error or a message from Cloudflare security. Does anyone have experience with this? I've been struggling with this for two days now. Any information that helps me move forward would be greatly appreciated.

Has anyone upgraded their n8n to the latest version and noticed issues whilst testing automations in workflow mode? particularly webhooks and forms In production mode everything seems to work fine, but when I try to 'execute workflow' in test mode to debug - either form pop-ups don't come up or the webhooks gives "The requested webhook \"bla bla\" is not registered.","hint":"Click the 'Execute workflow' button on the canvas," Am I missing something silly or is this an upgrade issue?, I also get these logs in the docker container on hostinger: Received request for unknown webhook: The requested webhook "bla bla" is not registered.

Hi @Nadia Privalikhina & @Serop B , I have a client project using n8n and I need some advice on the RAG setup. The client has 12 large textbooks (PDFs). I need to build an automation where the AI generates course lessons, but it must use only specific books or chapters as the source material (not the whole library at once). I know that you will teach us about this in the upcoming course, but I just want to quickly understand it because I need it right now. My questions: 1. What is the best strategy to "chunk" or split these large files? Should I split them by chapter before uploading? 2. How do I set up the metadata so the AI knows which book is which? 3. Are there any specific tutorials or resources you recommend for building a "Textbook RAG" system in n8n? Thanks in advance!

We’ve officially wrapped up Week 2 of the cohort, and what an amazing week it has been! 🚀 So far, we dove deep into n8n fundamentals and explored two real-world use cases me and Nadia have already sold to clients: ✨ Automated Proposal Generation ✨ Email Auto-Responder Systems It was incredible to see the group applying these skills so quickly and creatively. You submitted your homework, tackled brainstorming tasks, and pushed yourselves to build practical automations that bring real value.👏 Huge congratulations to everyone who submitted their work on time and an equally big shoutout to those still working hard to learn n8n and integrate AI into their daily workflows. Your effort, curiosity, and consistency are what make this community special. Let’s keep the momentum going, Week 3, here we come! 💡

So for the homework we have to respond to 2 scenarios. 1. Email to "hello@" being represented by a personal email. 2. An email from noreply@ with the specific subject and hello@ as CC. How are we supposed to mimic/test this second scenario with just a personal email? Just filter on cc + subject?
