Worked on the Chia-Network/chia-blockchain repository to enhance RPC error handling within the full_node_rpc_api. Developed a structured approach by introducing a dedicated RpcError class, enabling standardized error responses and improving the clarity of error communication between components. Refactored legacy error models, aligning them under a unified rpc_errors module and removing outdated fields to streamline code health. Addressed edge cases such as undefined service properties and empty error messages, ensuring greater stability. Expanded the unit test suite to cover a broader range of error scenarios, leveraging Python and API development skills to deliver more robust error handling and maintainable code.
