Why AI Agents in n8n Fail on Real-World Workflows (and How to Fix It)

The Gap Between the and the Real World The always works. You wire up an LLM node in n8n, chain a few HTTP requests, and the agent navigates through a multi-step workflow without a hitch. Then you point it at something real - a signup flow, a SaaS trial, a service that requires email verification - and the workflow halts. Not because the reasoning was wrong. The agent chose the right action. It decided to create an account. It selected the right form fields. It even generated a valid request. It failed because the service sent a verification email and the agent had no way to receive it.
