[Gemini] ValueError: The `response.parts` quick accessor only works for a single candidate, but none were returned. Check the `response.prompt_feedback` to see if the prompt was blocked.

원인 : 잘못된 request로 prompt 응답이 차단된 case 혹은 safety setting error 

 request 보내기 전에 parameter를 다 기입해준다. 현재로서는 max_tokens

• candidate_count : 출력 수 
• top_p : log_probabilities들의 argmax 값을 역순으로 정렬한뒤 단어 단위로 재구성 (글렀다_argmax : 0.7, 힘들다_argmax: 0.3)
  • 오늘 아침 먹기는 글렀다. 
  • 오늘 아침 먹기는 힘들다.
