This is more of a Vercel question. I followed the instructions [here](https://vercel.com/docs/functions/runtimes/python) to set up a serverless Python function. I am not using any server frameworks, just plain Python http server. It works fine in production, but when I run it locally (through vercel dev), it returns 404. How to fix it?
