codex - 💡(How to fix) Fix macOS app: stream disconnected before completion after image_generation_call events [2 comments, 2 participants]

stream disconnected before completion: An error occurred while processing your request... 2026-04-23 02:51:39 websocket error type=server_error request_id=7b68ddbe-13be-9caa-a7d5-5a71d25fdd82

• upstream error pasted into the thread: 173cb339-4dc3-4c8b-8392-11614ebb67a2 The turn should either continue streaming normally or fail with a handled and clear error state, without repeated disconnect retries and unhandled image-generation events.

TL;DR

The issue may be resolved by handling unhandled image_generation_call events and improving error handling for websocket server errors.

Guidance

• Investigate the cause of the failed to parse ResponseItem from output_item.added error, which may be related to the image_generation_call event.
• Handle the unhandled responses event: response.image_generation_call.in_progress and unhandled responses event: response.image_generation_call.generating events to prevent repeated disconnect retries.
• Review the error handling for websocket server errors, such as the websocket error type=server_error event, to provide a clear error state instead of retrying the request.
• Check if the issue is related to the one described in #19107 and consider applying any available fixes or workarounds.

Notes

The provided log excerpt suggests that the issue is related to the handling of image_generation_call events and websocket server errors. However, without more information about the Codex App's implementation, it is difficult to provide a more specific solution.

Recommendation

Apply workaround: Handle unhandled image_generation_call events and improve error handling for websocket server errors, as this may resolve the issue and prevent repeated disconnect retries.
