Bug Fixes

HTTP Status Code Handling

• Status Code Name Mismatch - Fixed critical issue in FastAPIExceptionHandler where http_status_code was incorrectly referenced
  • Changed from exception.http_status_code to exception.http_status_code_value for proper status code retrieval
  • Resolved HTTP status code name mismatch that was causing incorrect error responses
  • Improved error handling consistency in FastAPI exception processing

Improvements

Protobuf DTO Runtime Type Safety

• Runtime Type Checking - Enhanced BaseProtobufDTO with comprehensive runtime type validation
  • Added runtime type checking in from_proto() method to validate input parameter types
  • Implemented proper type validation before protobuf message processing
  • Enhanced error messages with clear type mismatch information

Custom Exception Integration

• Custom Exception Handling - Replaced generic TypeError with domain-specific InvalidEntityTypeError
  • Updated protobuf DTO type validation to use InvalidEntityTypeError for better error categorization
  • Improved error context with expected and actual type information
  • Enhanced error handling consistency across the protobuf DTO system

Code Quality Enhancements

• Error Handling Consistency - Standardized error handling patterns across protobuf DTO operations
  • Improved error message clarity and debugging capabilities
  • Enhanced type safety with proper exception chaining
  • Maintained backward compatibility while improving error reporting
