Refreshing `access_token` on SSR does not work

I've done a plugin/composable based on this doc: https://nuxt.com/docs/guide/recipes/custom-usefetch My composable useCustomFetch is exactly the same as the doc. And here is my customized plugin:

export default defineNuxtPlugin((nuxtApp) => {
  const config = useRuntimeConfig();
  const authStore = useAuthStore();
  let isRefreshing = false;
  let refreshAttempts = 0;

  const $customFetch = $fetch.create({
    baseURL: config.public.apiBaseUrl,

    onRequest({ options }) {
      const userAccessToken = useCookie("access_token").value;
      if (userAccessToken) {
        options.headers = options.headers || {};
        options.headers["Authorization"] = `Bearer ${userAccessToken}`;
      }
    },

    async onResponseError({ request, response, options }) {
      if (response.status === 401 && !isRefreshing) {
        isRefreshing = true;
        try {
          await authStore.refreshAccessToken();
          const newAccessToken = useCookie("access_token").value;
          if (newAccessToken) {
            options.headers = options.headers || {};
            options.headers["Authorization"] = `Bearer ${newAccessToken}`;
            console.log("Retrying request with new access token");
            isRefreshing = false;
            refreshAttempts = 0; // Reset attempts on successful refresh
            return $fetch(request, options);
          }
        } catch (e) {
          console.error("Token refresh failed:", e);
          isRefreshing = false;
          refreshAttempts++;
          if (refreshAttempts >= 1) {
            authStore.logout();
            navigateTo("/login");
          }
        }
      } else if (response.status === 401 && isRefreshing) {
        navigateTo("/login");
      }
      return Promise.reject(response._data);
    },
  });

  nuxtApp.provide("customFetch", $customFetch);
});

export default defineNuxtPlugin((nuxtApp) => {
  const config = useRuntimeConfig();
  const authStore = useAuthStore();
  let isRefreshing = false;
  let refreshAttempts = 0;

  const $customFetch = $fetch.create({
    baseURL: config.public.apiBaseUrl,

    onRequest({ options }) {
      const userAccessToken = useCookie("access_token").value;
      if (userAccessToken) {
        options.headers = options.headers || {};
        options.headers["Authorization"] = `Bearer ${userAccessToken}`;
      }
    },

    async onResponseError({ request, response, options }) {
      if (response.status === 401 && !isRefreshing) {
        isRefreshing = true;
        try {
          await authStore.refreshAccessToken();
          const newAccessToken = useCookie("access_token").value;
          if (newAccessToken) {
            options.headers = options.headers || {};
            options.headers["Authorization"] = `Bearer ${newAccessToken}`;
            console.log("Retrying request with new access token");
            isRefreshing = false;
            refreshAttempts = 0; // Reset attempts on successful refresh
            return $fetch(request, options);
          }
        } catch (e) {
          console.error("Token refresh failed:", e);
          isRefreshing = false;
          refreshAttempts++;
          if (refreshAttempts >= 1) {
            authStore.logout();
            navigateTo("/login");
          }
        }
      } else if (response.status === 401 && isRefreshing) {
        navigateTo("/login");
      }
      return Promise.reject(response._data);
    },
  });

  nuxtApp.provide("customFetch", $customFetch);
});

Everything is working quite well on CSR, but when I try to refresh my access_token from SSR I have an error that I can't resolve
