I've been working for months on a project that uses AWS Lambda + Python + FastAPI + Docker. I tried to debug a Lambda following several tutorials, AI, Medium articles, and YouTube videos without success. Almost all of them were obsessed with using AWS SAM, which I don't use at all. So I took advantage of a quiet Sunday afternoon in my dungeon (I mean basement), and finally found a way to make it work. I'll show you how below and I hope it helps you. 😉
