Seems dati.toscana.it absolutely wants some param in the GET:

http://dati.toscana.it/api/3/action/package_list gives "Richiesta non valida - Errore JSON: No request body data"

This doesn't work also:

http://dati.toscana.it/api/3/action/package_list?

By putting a random character such as 'a' after the '?' works:

http://dati.toscana.it/api/3/action/package_list?a

interesting behavior.. :confused:

"No request body data" should indicate missing json body.. what's the returned HTTP status code / relevant headers?

[rshk]

This is the point in which the exception is raised.. have fun debugging that code :P

Sorry, for once even Refine can be more fun than this. Forced the GET in curl, got same error:

now it works on dati toscana even without garbage parameters workaround, and I'm not much willing to put crap in the param list just to make this work on old ckan versions, so I'm closing it
