{Error code '498': 'Invalid Token'}

Anonymous User · ‎10-28-2015

Hi,

We are migrating our silverlight application from 9.3 to 10.3.

When we are trying to Query on a feature service. The following code works perfectly with ArcGIS server 9.3 service, but fails when we migrate the same service to 10.3. We used ArcGIS Silverlight API (that is 2.4Ver) in both the cases.

                     QueryTask queryTask = new QueryTask(boundaryDefinition.Url);
                      queryTask.Token = "municiaplities";
                      queryTask.ExecuteCompleted += QueryTask_ExecuteCompleted;
                      queryTask.Failed += QueryTask_Failed;

We observed that the failing in 10.3 happens at line queryTask.Token = "municiaplities"; If we remove this line it works in 10.3 also.

The error we received when it fails is this. {Error code '498': 'Invalid Token'}

But we have to use line with the Token.( it is required for us).

How to solve this error. We need this urgently.

Here is the API used.

ArcGIS silverlight API 2.4 for 9.3 as well as 10.3. We don't know if we have to use another version for 10.3

Here is the complete code.
