When I exported the header template part, which includes a navigation menu I received the following warning for each menu item that was invalid.
Warning: Attempt to read property "post_status" on null in C:\apache\htdocs\wp55\wp-content\plugins\gutenberg\build\block-library\blocks\navigation-link.php on line 114
