I'm noticing some inconsistency in the preview functionality. Some pages it works fine, and others I get a 500 error.

Here is a backend link for a page where the preview is working fine:

https://gnet.flywheelsites.com/wp-admin/post.php?post=1207&action=edit

And here is the preview link it generates:

https://gnet-fh.netlify.app/work/call-of-duty-black-ops-6-launch-trailer/?id=1207&type=page&status=publish&preview=true&slug=call-of-duty-black-ops-6-launch-trailer&uri=/work/call-of-duty-black-ops-6-launch-trailer/&_thumbnail_id=1308

Now here is a new page I just created in the backend:

https://gnet.flywheelsites.com/wp-admin/post.php?post=1664&action=edit

And here is the preview link it generates, which is showing me a 500 error:

https://gnet-fh.netlify.app/work/another-test-page/?id=1664&type=page&status=publish&preview=true&slug=another-test-page&uri=/work/another-test-page/

For some more context - I created this page earlier today:

https://gnet.flywheelsites.com/wp-admin/post.php?post=1605&action=edit

And the preview wasn't working there either. But now I'm checking it a few hours later, and now the preview is working fine. This makes me think that it needed to deploy for the preview to start working, which defeats the purpose of a preview right? Can we fix this so that the previews work before deploying?
