I am using Mediawiki 1.36.1 which, according the VisualEditor page, contains VisualEditor so I do not need to install it before enabling it. Furthermore, Parsoid is not required because MediaWiki >=1.35 is being used.

As per the documentation, I have added the following line to my LocalSettings.php:

wfLoadExtension( 'VisualEditor' );

I have restarted my server and editing any page results in:

Error contacting the Parsoid/RESTBase server: (curl error: 7) Couldn't connect to server

This is confusing because:

• First, the VisualEditor page states that Parsoid is not required because MediaWiki >=1.35 is being used.
• Second, it is not clear what server we're trying to connect to; why we're trying to connect to a server (we're just trying to edit some text).

It should be noted that my instance of MediaWiki is on Docker, so from my host machine, I can access MediaWiki from outside the container at http://0.0.0.0:8080, but http://0.0.0.0:8080 is not accessible from within the container.

I suspect that the requestRestbase() function in includes/ApiParsoidTrait.php attempts, for some reason, to contact itself at http://0.0.0.0:8080 (it can't), and results in an error.

Why is VisualEditor trying to do this? And how to get around this using Docker?
