It's not saying that it can't find the question and doesn't seem to be complaining about the json format that I've sent, but doesn't seem to be able to return the appropriate data. I've also tried adding a specific property to return but that doesn't seem to help.
Any thoughts on where the problem is? Is this potentially a problem specific to json rather than xml?
This works without a problem if I specify some fields in aQuestionSettings. Although it says that the default is null for aQuestionSettings, in which case all results are supposed to be returned, that is when I am getting the error.
This isn't crucial for me now that I see that I can specify the properties I want, I am just curious now why it isn't working.
