I am trying to run the query using the REST and Json calls. I keep getting this error.
"Unsupported type: System.String. Use the JsonSerializer class to get the object\'s JSON representation. Path \'results\'.
Attached is the sample PERL code I am using that is getting the above error.
The columns ancestordisplaynames and ancestordetailsurls returns array of display names and details urls, which is not supported in our JSON converter. Removing these columns from your query should solve the issue.
Will get back to you on including support for columns that returns array.
