Improve exception message

When is passed invalid filter the exception is very generic, maybe we can improve it.

Exception has occurred: CLR/Newtonsoft.Json.JsonReaderException
An exception of type 'Newtonsoft.Json.JsonReaderException' occurred in Newtonsoft.Json.dll but was not handled in user code: 'JsonToken EndArray is not valid for closing JsonType Object. Path ''
