ChatGPT login token missing api.responses.write scope

Environment

• Codex CLI: 0.142.5
• OS: Ubuntu
• ChatGPT Plus
• Personal organization
• Organization Owner
• Default project

Authentication

• Logged in using ChatGPT (codex login status)
• No OPENAI_API_KEY or any OPENAI_* environment variables
• Installed from the official npm package @openai/codex

Problem

After logging in with ChatGPT successfully, every prompt fails with:

401 Unauthorized
Missing scopes: api.responses.write

The access token only contains these scopes:

• openid
• profile
• email
• offline_access
• api.connectors.read
• api.connectors.invoke

It does not include api.responses.write.

Steps to reproduce

1. Install @openai/codex 0.142.5
2. Run codex login
3. Sign in with a ChatGPT Plus account
4. Run codex
5. Enter any prompt (for example: Hello)

Expected behavior

ChatGPT login should authorize Codex CLI to use the Responses API.

Actual behavior

Every prompt returns:

401 Unauthorized
Missing scopes: api.responses.write

Troubleshooting already performed

• Reinstalled Codex CLI from the official npm registry
• Logged out and logged in again
• Deleted ~/.codex/auth.json and logged in again
• Confirmed there is no OPENAI_API_KEY
• Confirmed I am the Organization Owner of the Personal organization

If needed, I can provide the request ID from the error message or run additional diagnostics.
