Hello, I'm trying to set up my FastAPI app on the Hobby plan and running into some issues which I think are easy to solve but I have little Vercel experience.

My repository has the following (somewhat atypical) structure

1
/api
2
   /routes
3
   /models
4
   connection.py
5
   main.py
6
/... other folders
7
.env
8
README.md
9
requirements.txt
10
vercel.json

So important here is that main.py isn't in the root directory (but in the /api directory). To make sure Vercel correctly picks up on where to find it, I have set up vercel.json like this:

1
{
2
  "builds": [
3
    {
4
      "src": "api/main.py",
5
      "use": "@vercel/python"
6
    }
7
  ],
8
  "routes": [
9
    {
10
      "src": "/(.*)",
11
      "dest": "api/main.py"
12
    }
13
  ]
14
}

However I get the following error screen with **500**: INTERNAL_SERVER_ERROR:

And the following log:

1
[ERROR] Runtime.ImportModuleError: Unable to import module 'vc__handler__python': No module named 'connection'
2
Traceback (most recent call last):INIT_REPORT Init Duration: 1330.54 ms	Phase: init	Status: error	Error Type: Runtime.Unknown

Inside main.py helper functions from connection.py are imported like this

1
from connection import get_driver

This all works fine on my local server but I think Vercel has issues with finding connection.py because it goes looking for it in the root directory? I'm not sure though, it's my best guess. How could I resolve this without moving everything in the /api folder to the root folder?
