Error Handling

Always keep SDK methods in try catch block. If exception message is Empty, then try to read the Inner exception message.

string Url = "https://machinename:Port/";

CancellationTokenSource cancelToken = new CancellationTokenSource();

try

{

var engineeringDataClient = DataApiClientFactory.CreateDataApiClient<EngineeringClient>(host: Url, authType: AuthenticationType.NTLM, waitingTimeInMinutesForLiveData: 3, token: string.Empty, cancelToken);

var listOfDataSources = await engineeringDataClient.GetDataSources(filter: "kept for future purpose (optional)");

}

catch (Exception ex)

{

string message = ex.Message;

if (string.IsNullOrEmpty(message))

{

message = (ex.InnerException != null ? ex.InnerException.Message : string.Empty);

}

Console.WriteLine($"Message:{message}");

}
