Codex OAuth failure across team: TypeError "'NoneType' object is not iterable"

We are seeing Codex OAuth failures across multiple team members. We are not using an OpenAI API key; this is ChatGPT/Codex OAuth.

Provider shown in logs: openai-codex Model: gpt-5.5 Endpoint: https://chatgpt.com/backend-api/codex Error: TypeError: 'NoneType' object is not iterable HTTP status: None Impact: Non-retryable error, Codex usage blocked across team.

Logs: API call failed (attempt 1/3): TypeError Provider: openai-codex Model: gpt-5.5 Endpoint: https://chatgpt.com/backend-api/codex Error: 'NoneType' object is not iterable Non-retryable error (HTTP None) — trying fallback... Non-retryable client error (HTTP None). Aborting.

Additional context:

  • Happening across my team, not isolated to one user.
  • OAuth Codex is being used, not API.
  • We also see context compression warnings and an OpenRouter 402 during compression, but the Codex failure is against chatgpt.com/backend-api/codex.
  • Please investigate whether the Codex OAuth backend is returning null/malformed data or whether the client is not handling a missing field.
