Description

Having issues with hosting the litestar application with a separate frontend.

Running pnpm run dev with litestar run -r works just fine.

Problem is getting this to production level infrastructure.

In my repository that I've linked, I place a caddy server infront of it and I end up receiving this error.

Access to fetch at 'http://localhost/accounts/login' from origin 'http://localhost:5173' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: Redirect is not allowed for a preflight request.
