Working on using distributed events, though what we're seeing is that not all events are being received as expected (half?):
What you're seeing:
- We're triggering a background job to be run from Web
- That background job is being run within the Api.Host
- When the background job is complete, we publish an event to notify the client (for the purpose of client-side notification)
- In some cases (approximately half?) the message is received and can be dealt with properly (in SignalR hub which then causes client-side handler to ultimately call
abp.notify - In other cases, nothing is occurring.
- ABP Framework version: v7.4.2
- UI Type: MVC
- Database System: EF Core (SQL Server)
- Tiered (for MVC) or Auth Server Separated (for Angular): yes
- Steps to reproduce the issue:
Here's the options:
Configure<AbpAzureServiceBusOptions>(options =>
{
options.Connections.Default.Admin.Retry.MaxRetries = 3;
options.Connections.Default.Client.RetryOptions.Delay = TimeSpan.FromMilliseconds(100);
options.Connections.Default.Client.RetryOptions.MaxDelay = TimeSpan.FromSeconds(10);
options.Connections.Default.Client.RetryOptions.Mode = Azure.Messaging.ServiceBus.ServiceBusRetryMode.Exponential;
options.Connections.Default.Client.RetryOptions.MaxRetries = 10;
});

hi
await _backgroundJobManager.EnqueueAsync<TestJobArgs>(new TestJobArgs() { Content = content, UserId = CurrentUser.Id, TenantId = CurrentUser.TenantId });This operator will store a job to the database, and the
BackgroundJobWorkerwill check the job and execute it every 5 seconds.It's not executed in real-time.

Yea, we understand that - that's by design. While we know the background job runs when it runs, the job itself pubs the distributed event - why doesn't the event get received half the time?
Ultimately, this is all just to notify a user when a job completes independent of the page they are on (as reporting jobs can take long) - if there's a better way, we're all ears - but there isn't AFAIK currently and this should work.

hi
The solution is to set
IsServiceBusDisabled = truein HTTP API module.
Yes, that seems to have done the trick. At the same time, for whatever reason, we also had to produce new keys. For some reason the default key that's created when you create the service bus doesn't work while a new key (created to be the same) works. Even scoped keys work (scoped to a topic), they also work.
Also, the "manage" permission is required or this'll be what happens:
