fix: remove redundant identity check in AttributeError test

- Removed 'mock_body is not None and value is None' redundant condition
- Simplified test to directly test AttributeError handling scenario
- Addresses linter warning about identity check that will always be True
- Maintains same test coverage while improving code quality
- Follows proper make format && make pr workflow validation
