--- Comment #11 from Thiemo Mättig thiemo.maettig@wikimedia.de --- Guys, you realize somebody needs to post an example API request that contains an error message and shows the wrong structure we are talking about? As I said, from what I know there is nothing wrong with the API. At the moment this looks like a coding error in Pywikibot to me. Which is nothing the Wikidata team can fix.
