--------------------------------------------------------------------------------------------------대충 해석을 해보았습니다. 위에 검은색 글씨의 에러부분은 트라이 캐치에서 찍어낸 에러입니다.

해석을 해보면. 받아온 accessToken이 잘못 되었다는 뜻 같습니다..(위,보라색부분)

그래서 다시 로그인 인증을 통해 accessToken을 다시 받고 새로운 토큰을 넣고 돌려보았는데도

계속 저 에러가 나더군요.. 그렇기에 토큰이 잘못되어 아래 널포인트를 야기 시키는것같습니다..

로그인 인증으로 인해 얻은 토큰의 사용법이 잘못되었을까요?

왜 저렇게 에러가 날까요..??-----------------------------------------------------------------------------------------------
