I'm using a JsonDataSource, InlineData, and I'm trying to edit/paste JSON in the data field. This is resulting in a 500-error stating that the parameter stream cannot be null. This only happens when I edit this data field. If I edit other parts of my report, everything is fine.
It seems like this is a front-end error, because if I set a breakpoint on the Save-function it seems to Base64-encode this field unless I try to edit it manually. If I paste in the data as Base64-encoded, it saves as normally and displays correctly upon refresh.
Is this a bug, or is there something wrong in my setup?
