I got a R2 2018 release of telerik reporting and excited about having Web Service Data Source option to connect to my OData REST service end point to retrieve the data.
Let's say that my web service endpoint responds below JSON:
"@odata.context": "My Context",
"ShippingName": "Eshmatov Eshmat",
If you look on an attached image, the data explorer contains a data source which have only two fields. The first is string (@odata.context) and second is Object (value).
For example, on report I want to have an access to City filed [=Fields.value.Address.City] or ShippingName field [=Fields.value.ShippingName]. This is not working and it is showing the System.Object  in report. As well in data explorer there is no way to see what fields the value field have.
Is it a bug, or it is designed for one level of json tree? Is there any workaround for this?
