📄 Description

Description

  • Fixed a bug where pipeline inlet/outlet filters silently corrupt the user's chat payload on HTTP errors. payload = await response.json() ran before response.raise_for_status(), so on HTTP errors, the user's chat payload was overwritten with the error response body. Moved raise_for_status() before response.json() in both inlet and outlet filter functions.

Fixed

  • Pipeline filters now properly raise HTTP errors before attempting to parse response, preventing silent chat payload corruption

Additional Information

  • Both process_pipeline_inlet_filter and process_pipeline_outlet_filter had the same issue
  • Tested by reviewing the code path and confirming the fix follows the correct error-handling order
  • Self-reviewed the code changes
