Resolved 💬 5 comments Opened Mar 25, 2026 by stephenlzc Closed Apr 4, 2026
What version of Codex is running?
Codex IDE extension from OpenAI (@ext:openai.chatgpt) in TRAE (VS Code fork).
Which model are you using?
N/A (UI fails before usable thread/sidebar interaction).
What operating system are you using?
macOS
Reproduction steps
- Install the official OpenAI Codex extension in TRAE.
- Open Command Palette and run
Codex: Open Codex Sidebar. - Observe no sidebar opens (no visible UI response).
- Check extension output/logs.
Expected behavior
Codex sidebar should be focused/opened successfully.
Actual behavior
No sidebar opens. Logs repeatedly show IPC warnings and explicit view-focus errors:
[warning] [IpcClient] Received broadcast but no handler is configured method=thread-stream-state-changed
[error] Failed to focus Codex view error="command 'workbench.view.extension.codexSecondaryViewContainer' not found"

Notes
This appears to be an IDE-compatibility issue in a VS Code fork where the extension expects a command id that is not available.
