There was QueryInterceptor, which filtered out some C models. That caused empty C property in some B elements in http://localhost:58362/DataService.svc/A?$expand=B/C/D. Trying expanding with D was breaking the result. Solution is to prepare QueryInterceptor, which does not filter C models in some situations or prepare QueryInterceptor for B. share|improve this answer answered Oct 16 '14 at 13:55 Arek Żelechowski 1,047619 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting y
on 2011/05/17 by admin Today I wanted to created simple out of a box Odata service using WCF Dataservice. My entry page was http://www.odata.org/ I watched couple of tutorials how to add service to mvc project. very simple and straight forward, but I failed getting message “ An error occurred while processing this request. ”. While trying to debug it by normal means and looking into logs bring me nothing which can help solve issue. I searched and find nice post http://blogs.msdn.com/b/phaniraj/archive/2008/06/18/debugging-ado-net-data-services.aspx explaining how to get error details. essentially you need just two steps: First set config.UseVerboseErrors = true in your service cs file 1: // This method is called only once to initialize service-wide policies. 2: public static void InitializeService(DataServiceConfiguration config) 3: { 4: // TODO: set rules to indicate which entity sets and service operations are visible, updatable, etc. 5: // Examples: 6: config.UseVerboseErrors = true; 7: config.SetEntitySetAccessRule("ExampleClass", EntitySetRights.AllRead); 8: // config.SetServiceOperationAccessRule("MyServiceOperation", ServiceOperationRights.All); 9: config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; 10: } Second: attribute your class with ServiceBehavior(IncludeExceptionDetailInFaults = true)] [System.ServiceModel.ServiceBehavior(IncludeExceptionDetailInFaults = true)] public class ExampleService : DataService< ExampleContext > Ok once this has been changed I got nice error: The server encountered an error processing the request. The exception message is ‘On data context type ‘ExampleContext', there is a top IQueryable property ‘Examples' whose element type is not an entity type. Make sure that the IQueryable property is of entity type or specify the IgnoreProperties attribute on the data context type to ignore this property.'. See server logs for more
