Worked on improving the reliability of the slackapi/bolt-python repository by addressing error handling in the Falcon adapter. Focused on backend development and API integration, the work involved updating the handling of not-found (404) responses to align with Falcon 3.x standards. Deprecated response methods were replaced with current Falcon APIs, ensuring that HTTP status codes and Content-Type headers were set correctly to prevent misinterpretation by downstream clients. Using Python and testing skills, the developer delivered a targeted bug fix that stabilized the integration, reduced production incidents related to error handling, and maintained compatibility with evolving backend frameworks and client expectations.
