GeodatabaseSyncTask.CreateAsync With credentials always return 401

[TércyoStorck1]

Hello,

When I try to create a GeodatabaseSyncTask with credentials it Always returns 401 unauthorized, even when the credentials are right. Here is the code that I'm using right now:

System.Net.NetworkCredential networkCredential = new System.Net.NetworkCredential(userName, passWord, domain);

            var credential = new ArcGISNetworkCredential
            {
                Credentials = networkCredential,
                ServiceUri = featureURI
            };
            
            GeodatabaseSyncTask gdbTask = await GeodatabaseSyncTask.CreateAsync(featureURI, credential);‍‍‍‍‍‍‍‍‍

I don't know if my code is wrong, but I've tried it on iOS (API100.0) and old .NET api and it worked fine!

Here is code that I used. Not 100% sure if you need both of the last two lines or not, but it should get you close enough that you can debug:

var featureServiceUri = new Uri(https://services6.arcgis.com/xxxxxx/arcgis/rest/services/zzzzzz/FeatureServer);

var credential = new ArcGISTokenCredential();
credential.ServiceUri = new Uri("https://services6.arcgis.com/xxxxxx/arcgis/rest/services");
credential.Password = Password;
credential.UserName = Username;

var creds = await AuthenticationManager.Current.GenerateCredentialAsync(credential.ServiceUri, Username, Password);

var gdbSyncTask = await GeodatabaseSyncTask.CreateAsync(featureServiceUri, creds);

// define an extent for the features to include
// Whole world extent, but project to web map before we can use it
var env = new Envelope(-179.99, -89.99, 179.99, 89.99, new SpatialReference(4326));
var extent = GeometryEngine.Project(env, new SpatialReference(102100)).Extent;

// get the default parameters for generating a geodatabase
var generateGdbParams = await gdbSyncTask.CreateDefaultGenerateGeodatabaseParametersAsync(extent);

// set the sync model to per layer
generateGdbParams.SyncModel = SyncModel.Geodatabase;

// do not return attachments
generateGdbParams.ReturnAttachments = false;

// create the generate geodatabase job, pass in the parameters and an output path for the local geodatabase
var generateGdbJob = gdbSyncTask.GenerateGeodatabase(generateGdbParams, GeodatabaseFile);

// handle the JobChanged event to check the status of the job
generateGdbJob.JobChanged += OnGenerateGdbJobChanged;

// start the job and report the job ID
var x = await generateGdbJob.CheckStatusAsync();
var zz = generateGdbJob.GetResultAsync();‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Does it really work for you? Because I've tried to get the credentials just like your code and got the same error.

It really does work. Not other suggestions other than checking to make sure your URLs are correct.
