whenever i request from the backend API, I get the folllwing error:

Access to fetch at 'https://uplink.mit.edu/users/me/lists' from origin 'http://localhost:5173' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

I don't think the error is about CORS, it just doesn't load at all even without JS sandboxing restrictions

The reason why it results in a CORS error is probably the fact that I'm not adding any headers from nginx and I'm just doing so from Python. I could change the nginx config to add the headers.

It also seems that the service crashes when you try to make a request

Okay so running api.py manually does work but the deployment I set with gunicorn just complains about the port being in use:

I started the development server temporarily, so I think it's running right now
