[Bug] Error serializing .pagination.currentPage

[johnd-dc3]

Bug Report

Describe the bug

On initializing the project, I receive the following error (full error statement below)

Error: Error serializing `.pagination.currentPage` returned from `getStaticProps` in "/".
Reason: `undefined` cannot be serialized as JSON. Please use `null` or omit this value.

Note that a simple solution is to remove the undefined value from pagination.current page in lib/posts.js. (This fixed the problem, but I'm not sure how to open a pull request!) Example fix (from posts.js):

  if (typeof page === 'undefined' || isNaN(page)) {
    page = 1;
  } else if (page > pagesCount) {
    return {
      posts: [],
      pagination: {
        currentPage,
        pagesCount,
      },
    };
  }

Is this a regression?

Not sure, have not tried on previous version

Steps To Reproduce the error

1. download the project via npm
2. Connect to Wordpress project via WPGraphQL
3. Wordpress project is on a local server for development. Using XAMPP locally.
4. Run npm run dev and I get the following error:

Server Error
Error: Error serializing .pagination.currentPage returned from getStaticProps in "/".
Reason: undefined cannot be serialized as JSON. Please use null or omit this value.

This error happened while generating the page. Any console logs will be displayed in the terminal window.
