I'm in the process of updating my Qt Quick (QML/javascript) app from API v2.1 to v3 and I've run into some trouble with Add movie rating method (and the other POST methods as well).

When XMLHttpRequest (xhr) readystate 4 is triggered then xhr.status = 0 and responseHeader status is '400 Bad request'.

Both request headers and the POST URL are, as far as I can see, set correctly. My session id is valid since I can access movie_watchlist etc. I've tried the example javascript code in the API documentation with the same result. Any suggestions?

Post url: http://api.themoviedb.org/3/movie/679/rating?api_key=####&session_id=####

Thanks
