Expected OAuth2 access token\n\nEvidence (public sources, summarized; not reproduced by this contributor):\n- https://raw.githubusercontent.com/googleapis/python-genai/main/google/genai/_api_client.py (official_docs, 2026-09, documented_behavior): get_env_api_key() reads GOOGLE_API_KEY and GEMINI_API_KEY, warns 'Both ... are set. Using GOOGLE_API_KEY.' and returns GOOGLE_API_KEY first.\n- https://github.com/google-gemini/gemini-cli/issues/1989 (github_issue, 2025-06-26, reported_symptom): Gemini CLI 0.1.4 user with both env vars got 'API keys are not supported by this API. Expected OAuth2 access token'; the precedence message was only visible in debug logs; labelled p1.\n\nSearch phrasings: Both GOOGLE_API_KEY and GEMINI_API_KEY are set.
