Perfect! I'll update the code to work with your migration. Here's the complete implementation:

Key Updates Made:

1. Fixed Sequelize Timestamps: Added proper createdAt and updatedAt mapping to match your migration's snake_case column names
2. Updated Field Names: All models now match your migration exactly
3. Proper References: Foreign key references are correctly set up
4. Error Handling: Comprehensive error handling throughout
5. Logging: Detailed console logging for debugging
6. Authentication: Mock authentication for development testing

Next Steps:

1. Run the migration: npx sequelize-cli db:migrate

2. Add to your server.js:

   const enrichmentRoutes = require('./routes/enrichment') app.use('/enrichment', enrichmentRoutes)

3. Set environment variables:

   • OPENAI_API_KEY
   • JWT_SECRET
   • NODE_ENV=development
4. Test with Postman: Use the collection I provided earlier

The code is now fully compatible with your migration and ready for testing! 🚀
