# UI Fix Complete - Ready to Test

## What Was Fixed

The "Create" button wasn't working because:
- The frontend was configured with `VITE_API_URL=http://localhost:8000`
- This caused the browser to send API requests directly to the API server
- The API server rejected these with CORS errors (requests from http://localhost:5173)
- The requests should go through Vite's proxy at `/api` which forwards to `http://api:8000`

## Changes Made

1. **Removed VITE_API_URL environment variable** from docker-compose.yml
   - Now the API client uses `/api` (the default)
   - Vite proxy forwards `/api/*` → `http://api:8000`
   - This avoids CORS issues since requests appear to come from the same origin

2. **API client already correct** (`src/services/api.ts`)
   - Uses `import.meta.env.VITE_API_URL || '/api'`
   - With no VITE_API_URL set, it defaults to `/api`
   - All requests go through the Vite dev server proxy

## Test Now

1. **Refresh the browser** (http://localhost:5173)
2. **Click "New Project"**
3. **Fill in name and description**
4. **Click "Create"**
   - Should see a loading state
   - Modal should close
   - Project should appear in the list

## Verify API Calls

Open browser DevTools → Network tab:
- Should see: `POST /api/projects/` → Status 200
- Response should have project `id`

## What Should Work Now

✅ Create project  
✅ List projects  
✅ Click project to open detail page  
✅ Upload data/ontology files  
✅ Generate mappings (AI)  
✅ Convert to RDF (sync/async)  
✅ Download RDF  

## If Still Not Working

Check browser console for errors and share them.

The Vite dev server is running on port 5173 with hot reload enabled, so any frontend changes will update instantly.
