Re: [Wikibase] Help with Direct Access on custom Wikibase

Hello. I am writing here to ask for help regarding a custom Repository/Client Wikibase installation i made locally. Just as a brief introduction: we already have a productive 15.000 pages custom wiki. Since it is quite data-intensive, we would like to implement Wikibase and migrate the more structured data there. Before going Wikibase on the productive Wiki, I setup a local machine for testing purpose and to gain experience on this extension. So I setup two MediaWiki instances: one with the Repository and Client extensions to act as "database" and the other one with only Client extension, intended to only consume data.

I read all the documentation I found and I was able to make everything work, although with some trial-and-error, but I can only read items with Arbitrary Access doing something like `{{#statements:P1|from=Q1}}`. Trying the Direct Access `{{#statements:P1}}` results in an empty string. I think I somehow miss something in Interwiki and/or SiteLink, so please help me here. Am I right that, in order to use Direct Access, I need to add a SiteLink in the Item page pointing to the page in the Client Wiki? I should create a link in the "Other Sites" group from the Repository wiki to the Client one? Am I right here? When I try to add the site to "Other sites" I can only see "wikidatawiki": I assume this is some kind of placeholder I should customize, but I do not know how to do it. I already setup the Interwiki linking between the two sites in the "interwiki" table of the databases.

What am I missing here?
