研究方向
Investigate the Python asynchronous client templates in the swagger codegen repository (likely under modules/swagger codegen/src/main/resources/python/). Look for how callbacks are currently implemented and identify where exceptions are not caught. Propose wrapping the callback call in a try except block and returning a custom error result object. Check the issue comments for any prior discussion or proposed approaches.
