This commit introduces stricter type validation across the application to reject objects with unexpected properties, enhancing the robustness and predictability of data handling. Changes include: - Implement a common utility to validate object types. - Refactor across various parsers and data handlers to utilize the new validations. - Update error messages for better clarity and troubleshooting.
