Subject: [PATCH] fix: enhance MongoDB client connection error handling

- Added a ping check after establishing a MongoDB client connection to ensure the connection is valid.
- Implemented error logging for ping failures to improve debugging and provide clearer feedback on connection issues.
- Ensured alignment with existing error handling practices in the codebase for consistency and maintainability.
