Hi,
I am using the .NET SDK to communicate with Backendless and have the problem, that it is not possible to add a listener on bulk events. When I try to add a listener to the real-time table, I get strange error messages in the console (see below).
Backendless Version (3.x / 5.x, Online / Managed / Pro )
Online (EU server)
Client SDK (REST / Android / Objective-C / Swift / JS )
Backendless.NET v6.2.0 (NuGet package)
Application ID
C450F07A-3B7E-D270-FF3E-285F049FCE00
Expected Behavior
I expect that the SDK subscribes to the real time data table and receives events when bulk updates are executed on the table.
Actual Behavior
When I subscribed to a real-time data table and use the AddBulkXXXListener methods to add a method that shall be called, if something was changed on the table, I can see the following error codes in the console windows:
BACKENDLESS LOG:Got result for subscription b89becc8-8879-4aaf-8d92-ccb0d8b72cc7
BACKENDLESS LOG:got error System.Collections.Generic.Dictionary2[System.Object,System.Object] BACKENDLESS LOG:Got sub res BACKENDLESS LOG:Got result for subscription b89becc8-8879-4aaf-8d92-ccb0d8b72cc7 BACKENDLESS LOG:got error System.Collections.Generic.Dictionary2[System.Object,System.Object]
BACKENDLESS LOG:Got sub res
BACKENDLESS LOG:Got result for subscription b89becc8-8879-4aaf-8d92-ccb0d8b72cc7
BACKENDLESS LOG:got error System.Collections.Generic.Dictionary2[System.Object,System.Object] BACKENDLESS LOG:Got sub res BACKENDLESS LOG:Got result for subscription b89becc8-8879-4aaf-8d92-ccb0d8b72cc7 BACKENDLESS LOG:got error System.Collections.Generic.Dictionary2[System.Object,System.Object]
Reproducible Test Case
Backendless.URL = configuration.BackendlessServerUrl;
Backendless.InitApp(configuration.BackendlessAppId, brokerConfiguration.BackendlessApiKey);
_logger.LogInformation("Backendless connection established.");
// configure database tables and realtime events
userTable = Backendless.Data.Of<User>();
userTableEventHandlers = userTable.RT();
// register bulk table events
userTableEventHandlers.AddBulkCreateListener(OnBulkUsersCreatedAsync);
private async void OnBulkUsersCreatedAsync(BulkEvent bulkEvent)
{
var users = await GetUsersFromBulkEventAsync(bulkEvent);
UsersCreated?.Invoke(this, new UserModificationBulkEventArgs(UserModificationType.Create, new User[0]));
}
