What happened?

Summary

/ui (SSO) returns 404 on non-root deployment when visiting /ui/login because the non-root image expects a prebuilt, folderized UI at /tmp/litellm_ui, but ships a flat bundle under /app/litellm/proxy/_experimental/out (e.g., login.html with no login/index.html). Runtime restructuring is skipped, so /ui/login 404s.

Environment

• Version/branch: v1.80.8-nightly
• Deployment: non-root image (LITELLM_NON_ROOT=true)
• Path to UI bundle in image: /app/litellm/proxy/_experimental/out
• SERVER_ROOT_PATH: unset
• Proxy was started normally (uvicorn/gunicorn entrypoint)

Steps to Reproduce

1. Deploy the non-root image with LITELLM_NON_ROOT=true.
2. Do not pre-populate /tmp/litellm_ui (default state of the image).
3. Hit https://<host>/ui/ → redirects to /ui/login.
4. /ui/login returns HTTP 404 ({"detail":"Not Found"}).

Observed

• In the container: /app/litellm/proxy/_experimental/out contains login.html but no login/ directory.
• /tmp/litellm_ui is absent, so nothing is mounted at /ui.
• Requests to /ui/login (or /ui/login/index.html) return 404.

Expected

• /ui/login should serve the login page without requiring manual pre-folderization or manual copying to /tmp/litellm_ui.
