I've tried to follow this guide but I get a Lua error on the Module:Wd. [[ https://www.tematichedigenere.com/wiki/Tematiche_di_genere:How_to_use_data_on_Wikimedia_projects | Here ]]I'm using the module and getting the error, the error message seems related to the line 196:

cfg.siteID = mw.wikibase.getGlobalSiteId()

The property mw.wikibase is null. Why? Is it a problem?

What should have happened instead?:

Software version (if not a Wikimedia wiki), browser information, screenshots, other information, etc.:
