# Task Log: Multi-Tenant Filtering & API Fixes

**Date:** 2025-01-27 12:45
**Mode:** beastmode

## Todo List Status

- [x] Step 1: Pipeline/Document routes multi-tenant filtering (completed earlier)
- [x] Step 2: Graph routes multi-tenant filtering (10 endpoints updated)
- [x] Step 3: Query/Retrieval routes multi-tenant filtering (3 endpoints updated)
- [x] Step 4: Update lightrag_server.py to pass rag_manager to all routes
- [x] Step 5: Fix API tab visibility - Add /static proxy for Swagger UI assets
- [x] Step 6: Fix "Network connection error" - Allow unauthenticated access when auth disabled
- [x] Step 7: Restart backend server to apply changes

## Actions
- Updated `graph_routes.py`: Added `get_tenant_rag` dependency to all 10 graph endpoints
- Updated `query_routes.py`: Added `get_tenant_rag` dependency to 3 query endpoints
- Updated `lightrag_server.py`: Pass `rag_manager` to `create_graph_routes()` and `create_query_routes()`
- Updated `vite.config.ts`: Added `/static` proxy to fix Swagger UI asset loading
- Updated `dependencies.py`: Fixed `get_tenant_context` to allow unauthenticated access when `auth_configured=False` and `api_key_configured=False`
- Restarted backend server to apply the authentication fix

## Root Cause Analysis

### Issue 1: API Tab White/Blank
- **Cause**: Swagger UI loads from `/docs` but assets come from `/static/swagger-ui/*`
- **Problem**: Vite proxy wasn't configured for `/static` path
- **Fix**: Added `/static` proxy in vite.config.ts

### Issue 2: Network Connection Error on Retrieval
- **Cause**: `get_tenant_context` in `dependencies.py` required authentication even when auth was disabled
- **Problem**: When frontend sends `X-Tenant-ID` header, `get_tenant_context_optional` calls `get_tenant_context` directly, which always requires auth
- **Fix**: Added check for `auth_configured` and `api_key_configured` in `get_tenant_context` - if both are False, allow guest access

## Decisions
- Used same multi-tenant pattern across all routes: `get_tenant_rag` dependency returns tenant-specific LightRAG instance
- For auth fix: Added guest user with "viewer" role when no auth is configured

## Next Steps
- Test all screens with tenant/KB switching to verify data isolation
- Verify API tab displays Swagger UI correctly
- Test retrieval queries work without authentication errors

## Lessons/Insights
- When `X-Tenant-ID` is provided in headers, `get_tenant_context_optional` propagates errors instead of falling back to None
- The auth logic in `dependencies.py` was inconsistent with `utils_api.py` - both now respect "no auth required" mode
- Swagger UI loads static assets from a separate path (`/static/`) that needs explicit proxy configuration

## Files Modified
1. `lightrag/api/routers/graph_routes.py` - Multi-tenant support for all graph endpoints
2. `lightrag/api/routers/query_routes.py` - Multi-tenant support for all query endpoints
3. `lightrag/api/lightrag_server.py` - Pass rag_manager to graph and query route creators
4. `lightrag/api/dependencies.py` - Allow unauthenticated access when auth is disabled
5. `lightrag_webui/vite.config.ts` - Added `/static` proxy for Swagger UI assets
