Unable to Sync Mobile Geodatabase to Feature Server Using C# ESRI SDK

rfrith3142 — Sat, 01 Jun 2024 17:13:48 GMT

Trying to sync a local mobile geodatabase to a feature server using ESRI C# SDK and WPF. The schemas match, there are no permission problems, the network is operational. Here's the code. Nothing revealed in the inner exceptions except vague messages that offer no insights. What's wrong with this code?

var LocalGeodatabasePath = "...";

var FeatureServiceUrl = "...";

try

{

// Load the local geodatabase

Geodatabase localGeodatabase = await Geodatabase.OpenAsync(LocalGeodatabasePath);

Console.WriteLine("Local geodatabase loaded.");

// Create the SyncGeodatabaseTask

var syncTask = await GeodatabaseSyncTask.CreateAsync(new Uri(FeatureServiceUrl));

Console.WriteLine("SyncGeodatabaseTask created.");

// Create the SyncGeodatabaseParameters

SyncGeodatabaseParameters syncParams = await syncTask.CreateDefaultSyncGeodatabaseParametersAsync(localGeodatabase);

// Check layers in the sync parameters

foreach (var layerOption in syncParams.LayerOptions)

{

Console.WriteLine($"LayerOption for layer {layerOption.LayerId}");

}

Console.WriteLine("SyncGeodatabaseParameters created.");

// Sync direction: Push local changes to the server

syncParams.GeodatabaseSyncDirection = SyncDirection.Bidirectional;

// Optionally, you can adjust other sync parameters here

// Create a job to synchronize the geodatabase

SyncGeodatabaseJob syncJob = syncTask.SyncGeodatabase(syncParams, localGeodatabase);

// Handle job status changes

syncJob.JobChanged += (s, e) =>

{

Console.WriteLine($"Job status changed: {syncJob.Status}");

if (syncJob.Status == JobStatus.Succeeded)

{

Console.WriteLine("Synchronization succeeded.");

}

else if (syncJob.Status == JobStatus.Failed)

{

Console.WriteLine($"Synchronization failed: {syncJob.Error.Message}");

}

};

// Start the job

syncJob.Start();

// Wait for the job to complete

var syncResult = await syncJob.GetResultAsync();

// Check for errors

if (syncJob.Status == JobStatus.Succeeded)

{

// Retrieve and store the replica ID

var replicaInfo = syncResult;

Console.WriteLine($"Synchronization complete. Replica ID: {replicaInfo.ToString()}");

}

else

{

Console.WriteLine($"Synchronization failed: {syncJob.Error.Message}");

}

catch (ArcGISWebException ex)

{

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

if (ex.InnerException != null)

{

Console.WriteLine($"Inner Exception: {ex.InnerException.Message}");

}

catch (Exception ex)

{

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

if (ex.InnerException != null)

{

Console.WriteLine($"Inner Exception: {ex.InnerException.Message}");

}

Job status changed: Started

Job status changed: Failed

Synchronization failed: Unable to complete operation.

Exception thrown: 'Esri.ArcGISRuntime.Http.ArcGISWebException' in mscorlib.dll

ArcGISWebException: Unable to complete operation.

Using:

ESRI.ArcGIS.Client

run-time version: 4.0.30319

version: 3.0.0.146

Feature service hosted on AGOL 10.91

Remote and local schemas match.

I do not see anything wrong with your code that could've led to this error. Just a suggestion (but likely not relevant to the error you're seeing) since you are awaiting the result of syncJob.GetResultAsync() already in a try-catch. There is no need to call syncJob.Start() or handle success/fail in JobChanged.

Based on the API name, I think you are using an older version of ArcGIS Maps SDK for .NET. One thing I would like to suggest (if you're able) is try the same request with latest 200.4. The equivalent event for JobChanged is StatusChanged. There is also a MessageAdded that could provide some insight at what stage this error happens (if it still happens).

There could be a number of things that could result to this generic server error. Are you able to inspect ArcGISWebException.Details property? According to this doc, one possibility is the replica GUID no longer exists on server. If you have access to the ArcGIS Server Logs, it may give more information on the GP Server error.

You can also see if you are hitting these support issues:

https://support.esri.com/en-us/knowledge-base/problem-unable-to-sync-services-in-arcgis-server-000027501

Another case that I've seen in my sync testing, it's possible for sync to fail to acquire the necessary lock to apply delta changes or have synchronization conflicts that need to be resolved.
