VS Code Codex extension: Usage settings page fails after ChatGPT re-login

What version of the Codex App are you using (From “About Codex” dialog)?

26.908.31748

What subscription do you have?

ChatGPT Plus

What platform is your computer?

Windows 11 x64

What issue are you seeing?

The Usage settings page in the VS Code Codex extension shows:

"无法加载使用设置"

This page worked before I signed out of ChatGPT. After signing in again, it stopped loading.

ChatGPT Web can load the Usage page normally using the same account. Codex conversations also work normally in VS Code.

Clicking Retry does not resolve the issue.

Environment:

• VS Code: 1.99.2
• Codex extension: openai.chatgpt 26.908.31748
• Authentication: Sign in with ChatGPT
• Platform: Windows 11 x64

The extension log repeatedly reports failures for these endpoints:

• /wham/usage
• /settings/user
• /wham/accounts/check

The requests show status=null.

Expected behavior:
The Usage settings page should load normally after signing in with ChatGPT.

What steps can reproduce the bug?

1. Open VS Code.
2. Open the Codex extension.
3. Sign in with ChatGPT.
4. Open Settings > Usage.
5. The page shows "无法加载使用设置".
6. Click Retry; the page still does not load.

What is the expected behavior?

No response

Reproduce the failure in the VS Code Codex extension by signing in again and opening Settings > Usage. Start by inspecting the extension logs for /wham/usage, /settings/user, and /wham/accounts/check, then trace the Usage settings page's handling of their status=null responses. Done means the Usage page loads after ChatGPT re-login and Retry succeeds.
