This issue is actually present in any page after installing the gutenberg integration plugin (tested with version 1.0.1), I just noticed it in a freshly installed Wordpress istance on an empty website.

Steps to reproduce

1. install the gutenberg integration plugin
2. set define( 'WP_DEBUG', true ); in wp-config
3. create a new page or post and edit with oxygen
4. save the page and check the frontend

You'll see the error message: "Undefined index: tag in /oxygen/component-framework/includes/cache.php on line 699"

this looks fixed to me in 3.1
