gemini 오류관련 질문드립니다.

안녕하세요, 강의 반복중에 있습니다.

이번에는 gemini로 RAG를 구축해보려고 하는데,

API Key를 활성화했음에도 계속 하기와 같은 에러가 뜹니다.ㅠ 제가 놓친 부분이 있을까요?

from langchain_google_genai import ChatGoogleGenerativeAI

llm = ChatGoogleGenerativeAI(
    model="gemini-2.0-flash",
    temperature=0,
    max_tokens=None,
    timeout=None,
    max_retries=2,
    # other params...
)

llm.invoke("인프런에 어떤 강의가 있나요?")
