Google provider authHeader:true returns 400 Missing Authentication

증상

Setting authHeader: true in Google provider config causes all API calls to return 400 “Missing or invalid Authentication”. Standard API key authentication fails.

원인

The authHeader flag is not correctly injecting the Authorization header for Google API requests. The provider implementation may expect a different header format.

해결법

Google Provider 인증 실패 해결

  1. authHeader: true 대신 API 키를 query parameter로 전달
  2. 설정에서 authHeader 제거하고 apiKey 직접 지정
  3. Google API는 Authorization: Bearer 대신 x-goog-api-key 헤더 사용
  4. 환경변수 확인: GOOGLE_API_KEY 또는 GEMINI_API_KEY 설정

예상 토큰 절약
