Enhance error detection and fallback triggering

- Added more comprehensive error detection for API responses
- Check for empty/null responses, JSON decode failures, and various error strings
- Ensure fallback method is called in all failure scenarios
- Added HTTP response failure handling
- Made fallback more aggressive to handle edge cases
