SDKs call method does not return the expected output

Postby anurage0 » 13 Aug 2019, 06:52

Currently after studying the demos and examples provided by Unified Automation documentation. I was able to write a simple code which connects to a server end point and calls a method. But sadly that method does not return the expected out. Moreover, if I call the same method on the same server and the same URL with the same parameters through the UAExpert I get the expected result. I am at my wits end and would appreciate any help below is the code that I have currently written.
Do let me know if i have missed anything in the code.
Code: Select all
public void Connect(string endpointUrl)
            AppSession.UserIdentity = new UserIdentity();
            AppSession.Connect(endpointUrl, SecuritySelection.None);           
            /// [Step 1]
            // parse the object id.
            NodeId objectId = NodeId.Parse("ns=2;i=15108");
            // get the selected method id.           
            NodeId methodId = NodeId.Parse("ns=2;i=15057");
            // get input arguments.
            UInt32 a = 2;
            List<Variant> inputArguments = new List<Variant>
                new Variant(), new Variant(a,TypeInfo.Scalars.UInt32), new Variant(),
                new Variant(), new Variant()
            /// [Step 2]
            List<StatusCode> inputArgumentErrors = null;
            List<Variant> outputArguments = null;
            // call the method on the server.
            StatusCode error = AppSession.Call(
                new RequestSettings() { DiagnosticsMasks = DiagnosticsMasks.None, OperationTimeout = 10000 },
                out inputArgumentErrors,
                out outputArguments);

There are no exceptions that are returned in the code by the server all input arguments are good and so is the error status.
