codex - 💡(How to fix) Fix VS Code extension fails to hydrate thread when rollout JSONL ends with dangling task_started [1 comments, 2 participants]

TL;DR

The UI should be modified to handle incomplete turns by treating the final dangling task_started as interrupted or aborted, allowing the thread to hydrate even when the final turn is incomplete.

Guidance

• The issue is likely caused by the UI's assumption that every task_started event has a corresponding terminal event, which is not always the case when the UI/process exits or disconnects mid-turn.
• To verify the issue, inspect the local Codex state and check if the rollout JSONL ends with a task_started event without a matching task_complete or turn_aborted event.
• To mitigate the issue, the UI could be modified to automatically append a task_complete event for dangling turns when loading the thread, similar to the manual workaround described.
• The UI's hydration logic should be updated to tolerate or recover from semantically incomplete JSONL data, rather than failing when encountering a dangling turn.

Example

No code snippet is provided as the issue does not contain sufficient information about the UI's implementation details.

Notes

The provided information suggests that the issue is specific to the UI's handling of incomplete turns, and the workaround of appending a task_complete event for dangling turns is effective in resolving the issue.

Recommendation

Apply workaround: The recommended solution is to modify the UI to handle incomplete turns by treating the final dangling task_started as interrupted or aborted, allowing the thread to hydrate even when the final turn is incomplete. This approach is based on the provided workaround and the expected behavior described in the issue.
