Not fetching on initial load, but fetches on revalidateOnFocus

[jeremytenjo]

Not fetching on initial load, but fetches on revalidateOnFocus. Why could this be?

  const fetcher = async () => {
    let cachedData = cacheId ? localStorage.getItem(cacheId) : false
    cachedData = cachedData ? JSON.parse(localStorage.getItem(cacheId)) : null

    if (cachedData) {
      hydrateCache()
      return cachedData
    } else {
      try {
        const fetchedData = await fetchContentful()
        cacheId && hydrateCache(fetchedData)
        return fetchedData
      } catch (error) {
        console.log(error)
        throw error
      }
    }
  }

Could you create a CodeSandbox to replicate it?
