- Backend: Downgrade Pydantic from v2 to v1.10.13 for compatibility
- Backend: Fix ObjectId to string conversion in user service
- Backend: Update config to use pydantic BaseSettings (v1 import)
- Frontend: Downgrade ESLint packages for compatibility
- Frontend: Configure Vite proxy to use 127.0.0.1 instead of localhost
- Frontend: Set API client to use direct backend URL (127.0.0.1:8101)
- Frontend: Add package-lock.json for dependency locking
This resolves MongoDB connection issues and frontend-backend
communication problems caused by localhost resolving to IPv6.
Verified: Login and dashboard functionality working correctly.

This commit migrates all models to Pydantic v2 and adds comprehensive
testing infrastructure for the news-engine-console backend.
Model Changes (Pydantic v2 Migration):
- Removed PyObjectId custom validators (v1 pattern incompatible with v2)
- Changed all model id fields from Optional[PyObjectId] to Optional[str]
- Replaced class Config with model_config = ConfigDict(populate_by_name=True)
- Updated User, Keyword, Pipeline, and Application models
Service Changes (ObjectId Handling):
- Added ObjectId to string conversion in all service methods before creating model instances
- Updated UserService: get_users(), get_user_by_id(), get_user_by_username()
- Updated KeywordService: 6 methods with ObjectId conversions
- Updated PipelineService: 8 methods with ObjectId conversions
- Updated ApplicationService: 6 methods with ObjectId conversions
Testing Infrastructure:
- Created comprehensive test_api.py (700+ lines) with 8 test suites:
* Health check, Authentication, Users API, Keywords API, Pipelines API,
Applications API, Monitoring API
- Created test_motor.py for debugging Motor async MongoDB connection
- Added Dockerfile for containerized deployment
- Created fix_objectid.py helper script for automated ObjectId conversion
Configuration Updates:
- Changed backend port from 8100 to 8101 (avoid conflict with pipeline_monitor)
- Made get_database() async for proper FastAPI dependency injection
- Updated DB_NAME from ai_writer_db to news_engine_console_db
Bug Fixes:
- Fixed environment variable override issue (system env > .env file)
- Fixed Pydantic v2 validator incompatibility causing TypeError
- Fixed list comprehension in bulk_create_keywords to properly convert ObjectIds
Test Results:
- All 8 test suites passing (100% success rate)
- Tested 37 API endpoints across all services
- No validation errors or ObjectId conversion issues
