Option: Log in once interactively to cache credentials, or use GEMINI_API_KEY / Vertex / ADC for CI. [evidence: official_recommended_action]
Applies when: Running gemini non-interactively (CI, -p, piped) with Google login auth and no cached credentials
Steps:
1. Run gemini interactively once and complete login.
2. In CI set GEMINI_API_KEY or configure ADC/Vertex auth.
3. Use NO_BROWSER=true only from an interactive terminal (copy the URL and paste the code).
Expected: The error no longer appears.
