If the example is cloned and ran with no further setup (no environment variables set up), it will error out because `extractPostEntries` will return `undefined` which can not be serialized by `getStaticProps `. This PR basically ensures that we return an empty array instead of the `undefined` for a collection of posts, and a `null` instead of the `undefined` for a single post.
