Oxygen/Gutenburg breaks when slug is changed on a page post

[heckyeah]

Hi,

So the issue that happens for me is when I change a page slug the Gutenburg editing area breaks. And in place of the editable content is this message:

Your site doesn’t include support for the "oxygen-vsb/ovsb-zipline-2" block. You can leave this block intact or remove it entirely.

Now the zipline-2 references the original slug of the page, and brings this error up when I change the slug.

Please, Help

OK so one fix i found was to install the Duplicate Page plugin and then duplicate the page and change the slug of the duplicated page then delete the old page.

Another fix i've found is that you can change the slug, update the page then uncheck Make this full page editable in gutenburg then update again. Now recheck Make this full page editable in gutenburg and click update again then the slug will change and the everything works again.

These are not fixes to the issue but they are work around that work.

This bug has persisted since 2020. And this isn’t some obscure edge case. It’s a basic, routine action—changing a page slug—that effectively renders the editor unusable... are you kidding me?

While developers can find workarounds, the whole purpose of Gutenberg is to give clients a straightforward, self-manageable experience. But they can’t do that when something as fundamental as a slug update breaks the editor entirely. It defeats the core purpose of having Gutenberg as a tool for client autonomy.

Unacceptable oxygen.
