Hi everyone. Please, I'd like some help understanding something. I'm a beginner in automation, and my first challenge is to create an AI agent for WhatsApp. I created an application on developer.facebook.com and connected it to the n8n WhatsApp Business "on message" node. When I click on "execute a test event" and send a message, the node doesn't trigger. I put the application live and publish the workflow, and I run more tests, but still nothing. Please help me understand the underlying issue so I can fix it. I installed my n8n on EC2 (I got help from Chat GPT to complete the installation). Do you think the problem might be related to that? Thank you.

Hey Automators! 👋 I’m a Machine Learning Engineer, and like most of you, I love automating everything... except my taxes. I realized many like me were losing hundreds of dollars in write-offs every year simply because they couldn't find the photo of a receipt buried in their gallery from 6 months ago. Standard OCR just gives you a messy text file. I wanted something smarter. So I built Rekeepo. It’s an AI search tool where you can just type "Furniture," "Lumber," or "Starbucks" and it finds the exact image in a split second using custom Vision-AI. I need your expert "Automation Brains" for two things: 1. Validation: Besides Handymen and Airbnb hosts, which industries do you think are "bleeding money" because of messy paper trails? (Lawyers? Field Sales? Trucking?) 2. The "Next Step": I'm thinking of building an n8n node or a Zapier integration next so this data can flow directly into Xero/Quickbooks. Would that be a game-changer for your clients? Side note for the group: I specialize in the "hard stuff" that no-code tools sometimes struggle with—Custom Python nodes, RAG (Talk to your data), and complex AI Agents. If you're stuck on a client project that needs a custom ML "brain" or advanced document processing, drop a comment or DM me. I’d love to help unblock you while I continue building Rekeepo! What should I build next to make this even more useful? 👇
