Description
```tsx
setIsLiked(
!![res.data][0].artistDetail.likes.find(
(el) =>
el === JSON.parse(localStorage.getItem('lumiereUserInfo'))._id,
),
);
```
위 코드를 아래와 같이 바꾸면 해결된다.
```tsx
setIsLiked(
!![res.data][0].artistDetail.likes.find(
(el) =>
el === JSON.parse(localStorage.getItem('lumiereUserInfo' || '{}'))._id,
),
);
```
