I've checked the RESTbase Docs in https://wiki.therofl98.co/api/rest_v1/ and tested conversion from HTML to Wikitext. When I input HTML, page title, and revision, it returns a 400 with a message similar to
{
"type": "https://mediawiki.org/wiki/HyperSwitch/errors/bad_request",
"method": "post",
"detail": "No or invalid If-Match header supplied, or missing mw:TimeUuid meta element in the supplied HTML.",
"uri": "/wiki.therofl98.co/v1/transform/html/to/wikitext/test/1"
}I'm having this problem on a self hosted MediaWiki installation, located here. To reproduce, you begin editing a page in VisualEditor. You make some edits on the page, but don't save it just yet. You switch to the Wikitext editor to see how that version looks, and make adjustments. You then switch back to Visual to see how it looks, and make further adjustments. After this, when you try to switch to Wikitext, Error loading data from server: apierror-visualeditor-docserver-http. pops up, and the RESTbase log reports something similar to this:

It appears it's now giving me a new error.
