This is a regression from T203696.

Our wikidata linking works as follows:

mw.loader.using( [
			'wikibase.api.RepoApi',
			'wikibase.client.currentSite',
			'wikibase.client.getMwApiForRepo',
			'jquery.wikibase.linkitem'
		] ).then( function () {
			mw.hook( 'mw.cx.translation.published' ).add( addWikibaseLink );
		} );

Now the RL module wikibase.client.currentSite does not exist

@Ladsgroup, Need some help here. I guess the above list of modules are no longer needed, and I can just use

mw.loader.using( [
            'jquery.wikibase.linkitem'
        ] )

( The need to import a jquery module is weird, Ideally I should just load a module like wikibase.client.PageConnector, but I guess this is a consequence of removing modularity for reducing RL modules)

Then

var repoApi = new wikibase.api.RepoApi( wikibase.client.getMwApiForRepo() );

is supposed to work. But it is throwing error: TypeError: repoConfig is null from wikibase.client.getMwApiForRepo.js

MODULE.getMwApiForRepo = function () {
		var repoConfig = mw.config.get( 'wbRepo' ),
			repoApiEndpoint = repoConfig.url + repoConfig.scriptPath + '/api.php';

		return wikibase.api.getLocationAgnosticMwApi( repoApiEndpoint );
	};

Which RL module I need to load for getting mw.config.get( 'wbRepo' ), working?

I was testing the above code in https://en.wikipedia.beta.wmflabs.org. In https://en.wikipedia.org, jquery.wikibase.linkitem does not come with wikibase.client.getMwApiForRepo.js - (is that a bug?)

You need to add 'mw.config.values.wbRepo' as dependency as well. Something along the lines of:

mw.loader.using( [
            'jquery.wikibase.linkitem',
            'mw.config.values.wbRepo'
        ] )

The fix has landed with 1.34.0-wmf.24 (deployed on 18 Sep for group 1 wikis like Catalan Wikipedia), but linking to Wikidata is still not working.
Check out some of translations made on 25th of September. Timestamps of when article is created with Content Translation and when that article is linked to Wikidata are not matching. In the two examples, different user has added Wikidata link.

• Talal Derki is created on 01:21, 25 Sep 2019‎ (UTC+2), but article is linked on 07:11, 25 Sep 2019‎ (UTC+2) by a different user
• Similar example can be seen with creation of "Of Fathers and Sons" and its linking to Wikidata.

By looking at one of the last articles published before 1.34.0-wmf.20 was deployed, we see that time and author of article creation and Wikidata linking are the same.

Edit: There are many examples of articles created with Content Translation (after deployment of 1.34.0-wmf.24) which are not linked to Wikidata, meaning no one did it manually. I'm not providing examples, as someone might link the page to Wikidata in the meantime.

, this was done manually by that user, right?

Yes, another user linked your new article to Wikidata item.
Patch 539222 to fix this problem for the second time was deployed with 1.34.0-wmf.25 and Wikidata linking is still not working.

Was there any js error in console while publishing?

I have double checked and Wikidata linking is working automatically after publishing again.
