I have Kafka messaging and Outbox event enabled in my solution. When I run application local it is refusing to connect. Please refer below log history of the project

    System.ArgumentNullException: Value cannot be null. (Parameter 'serviceType') at System.ThrowHelper.Throw(String paramName) at Microsoft.Extensions.DependencyInjection.ServiceProviderServiceExtensions.GetRequiredService(IServiceProvider provider, Type serviceType)

    It seems that you don't have the correct configuration of the Outbox/Inbox.

    Configure<AbpDistributedEventBusOptions>(options =>
    {
        options.Inboxes.Configure(config =>
        {
            config.UseDbContext<YourDbContext>();
        });
    });
    
    Configure<AbpDistributedEventBusOptions>(options =>
    {
        options.Outboxes.Configure(config =>
        {
            config.UseDbContext<YourDbContext>();
        });
    });

    Hi,

    You can configure it in the EntityFrameworkCoreModule instead of ApplicationModule.

    Please check the document: https://docs.abp.io/en/abp/latest/Distributed-Event-Bus#pre-requirements

    Hi I have done the same, now the Application is running properly. But I dont see any records getting added in "AbpEventOutbox" which is created by ABP for outbox events when I modify/create entities.

    Hi,

    Could you share a project that can reproduce the problem? I will check it. my email is shiwei.liang@volosoft.com

    Hi,

    I checked the project you provided. Because it does not configure any event bus, it uses LocalDistributedEventBus by default.

    The LocalDistributedEventBus will not use the outbox, It will publish the event directly.

    • First, you need to Enable for all entities:
    Configure<AbpDistributedEntityEventOptions>(options =>
    {
        options.AutoEventSelectors.AddAll();
    });
    
    • Configure a provider RabbitMQ&Kafka...

    Now you can see the records, but you need also to configure the inbox. otherwise your application will get stuck

    Hi, I have implemented Inbox also still application is getting stuck when saving. And I have observed one behavior when I do a Save operation the application gets stuck but after some time few thousands of records are getting added in AbpEventOutbox table but after some time these records get disappeared in the table. Also these thousands of records are published to a Kafka topic I have configured.

    Sample record that got added to AbpEventOutbox : { Id: DEE8596B-83BC-D8FC-44E3-3A0D7201312B ExtraProperties : {} EventName : Volo.Abp.Domain.Entities.Events.Distributed.EntityEto.Created EventData : {"entity":{"entityType":"Volo.Abp.EntityFrameworkCore.DistributedEvents.OutgoingEventRecord","keysAsString":"b2c05e79-323d-259b-cfa7-3a0d614ef330","properties":{}}}
    }

    Note: EventData is converted from byte to string

    But I don't see any records getting added in AbpEventInbox table.

    How should I proceed furthur.

    An exception occurred while iterating over the results of a query for context type 'Inventory.Location.EntityFrameworkCore.LocationDbContext'. Microsoft.Data.SqlClient.SqlException (0x80131904): A transport-level error has occurred when receiving results from the server. (provider: Session Provider, error: 19 - Physical connection is not usable)

    It seems like a problem with SQLServer server, Can you check if your database is available?

    BTW, please remove MultipleActiveResultSets=true from the connection string and try again.

    You can check the possible solutions through Stackoverflow: https://www.google.com/search?q=Session+Provider,+error:+19+-+Physical+connection+is+not+usable+site:stackoverflow.com&sca_esv=562631641&sxsrf=AB5stBgTK6JcsoYTNzXjy6T0y2ufl13HQg:1693878429576&sa=X&ved=2ahUKEwiTntnwrJKBAxUWr1YBHcOGAwcQrQIoBHoECBMQBQ&biw=1920&bih=857&dpr=2
