TinaCms Edit Text Error

[CryRtex]

Hi; Creating a space in vercel to use the theme today. I seem to get an error in the blog section when I do it on TinaCms

``Tina caught an error while updating the page:

Cannot read properties of null (reading 'getPostsDocument')

If you've just updated the form, undo your most recent changes and click "refresh". If after a few refreshes, you're still encountering this error. There is a bigger issue with the site. Please reach out to your site admin.``
