Hi, I have the same issue. I have logged a bug http://community.jaspersoft.com/jasperreports-server/issues/3286 but had no response. Let me know if you make any progress, but it is the API not returning what the web page needs. Regards, Michael
We have the same issue. We cannot get any options on any of our our scheduled reports as the REST web service is 404 not found for that reports options.
