Error Message

In the Windows Codex App settings, both the Browser page and the Computer use page show this error: I also hit what appears to be the same issue when Codex asked me to install/authorize the GitHub connector. After I approved the install prompt, Codex opened the browser. When the browser flow returned to Codex, the flow failed with the same kind of error. 4. Observe the error panel: 6. Observe the same error. The Browser and Computer use settings should load normally, and the GitHub connector authorization/install return flow should complete without the vertical enum/variant error.

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

Microsoft Windows NT 10.0.26200.0 x64

What issue are you seeing?

In the Windows Codex App settings, both the Browser page and the Computer use page show this error:

Invalid request: unknown variant 'vertical', expected one of 'local', 'workspace-directory', 'shared-with-me'

This appears in the UI instead of the expected browser/computer-use settings.

I also hit what appears to be the same issue when Codex asked me to install/authorize the GitHub connector. After I approved the install prompt, Codex opened the browser. When the browser flow returned to Codex, the flow failed with the same kind of error.

What steps can reproduce the bug?

  1. Open Codex App on Windows.
  2. Go to Settings.
  3. Open Browser.
  4. Observe the error panel: Invalid request: unknown variant 'vertical', expected one of 'local', 'workspace-directory', 'shared-with-me'
  5. Open Computer use.
  6. Observe the same error.
  7. Ask Codex to install/authorize the GitHub connector.
  8. Approve the prompt.
  9. Codex opens the browser for the authorization/install flow.
  10. After the browser flow returns to Codex, the flow fails.

What is the expected behavior?

The Browser and Computer use settings should load normally, and the GitHub connector authorization/install return flow should complete without the vertical enum/variant error.
