尝试创建localStorage不起作用（NextJS）

Question

我需要将清单数据拉到我的NextJS应用程序中，然后尝试将这些数据存储到localStorage，但从未设置过。我在做什么错了？

if (process.browser && localStorage.getItem('inv') === undefined) {
    const inv = await getInventory()
    localStorage.setItem('inv', inv)
  }

getInventory（）只是一个节点脚本，可从远程api中提取清单数据并返回fullInventory。

这是getInventory（）中的代码：

const getInventory = async () => {
  const token = await refreshToken()
  const header = {
    Authorization: `Bearer ${token}`,
  };

  const queries = await getQueriesCount();

  axios.interceptors.response.use(function (response) {
    return response;
  }, async function (error) {
    await new Promise(function (res) {
      setTimeout(function () { res() }, 2000);
    });

    const originalRequest = error.config;

    if (error.response.status === 401 && !originalRequest._retry) {
      originalRequest._retry = true;
      const refreshedHeader = await setHeader()
      axios.defaults.headers = refreshedHeader
      originalRequest.headers = refreshedHeader
      return Promise.resolve(axios(originalRequest));
    }
    return Promise.reject(error);
  });

  let fullInventory = [];

  for (let i = 0; i < queries; i++) {
    setTimeout(async () => {
      try {
        const res = await axios({
          url: `${MyApi}/Item.json&offset=${i * 100}&customSku=!~,`,
          method: "get",
          headers: header,
        });

        console.log(`adding items ${i * 100} through ${(i + 1) * 100}`);
        const items = await res.data.Item;
        items[0]
          ? (fullInventory = fullInventory.concat(items))
          : fullInventory.push(items);

        if (i + 1 === queries) {
          return fullInventory;
        }
      } catch (error) {
        console.error("We have a problem here: ", error.response);
      }
    }, 2000 * i);
  };
}
