Hotel Booking App API Data Retrieval Fix

I'm encountering serious data retrieval issues with my hotel booking app. The app is failing to retrieve data across all sections - user bookings history, available rooms list, and payment details. As a result, users cannot see their past bookings, the current availability of rooms, or their payment information. This is a critical problem that needs urgent attention.

Ideal candidates for this project should have:
- Extensive experience in app development and troubleshooting
- Strong skills in data management and retrieval
- Previous experience with hotel booking apps would be a plus
- Ability to work quickly and efficiently to resolve this urgent issue.
