workspace 값이 읽히지 않습니다.(prototype)

채널에서 워크스페이스 정보가 뜨지 않아 검사 창을 열어보니, 제 UserData 객체에 Workspace객체가 없고, prototype 객체가 하나 있는 것을 발견했습니다.

이후 네트워크에서 값을 확인해보니, 서버는 user의 data에 정상적으로 워크스페이스를 보내고 있는 것도 확인했습니다.

혹시나 싶어, 새 워크스페이스를 만들어서 보내도 서버에서는 정상적으로 처리해주었지만, 클라이언트에선 전혀 받지 못하고있습니다. 이럴 경우 어떻게 처리해주어야 하는지 여쭤보고싶습니다.

워크스페이스 부분의 코드를 첨부하며 리액트(+dom)의 버전은 17, axios의 버전은 0.26.1, swr의 버전은 2.0.3 입니다.

export default Workspace;

또, fetcher의 문제일 수 있을 것 같아, fetcher의 코드 또한 올려봅니다.

import axios from 'axios';
import React from 'react';


const fetcher = <Data,>(url: string): any => {
  axios.get<Data>(url, { withCredentials: true }).then((response) => response.data);
};

export default fetcher;
