System.Reflection.TargetException In Queuing Events about coravel

[jamesmh]

Thanks for all the details! I've run into this before so I know where it's happening but will need to figure out why....

Could you share the general shape of your PurchaseCreatedEvent? (just the method signatures)

Also:

• is the PurchaseCreatedEvent in the same project as your web or executable project?
• if not, what type of project is it (.NET Standard 2.0?, etc.)

Thank you for the quick replay. The shape of the PurchaseCreatedEvent is

public class PurchaseCreatedEvent : IEvent
    {
        public Organisation Organisation { get; set; }

        public Purchase Purchase { get; set; }

        public PurchaseCreatedEvent(Organisation organisation, Purchase purchase)
        {
            Organisation = organisation;
            Purchase = purchase;
        }
    }

1. It is in the same project.

[jamesmh]

What do your listeners look like? Are they in the same project also?

[khabubu]

The listener(s) are in the same project as illustrated below

public class PurchaseCreatedListener : IListener<PurchaseCreatedEvent>
    {
        private readonly ApplicationDbContext _context;

        public PurchaseCreatedListener(ApplicationDbContext context)
        {
            _context = context;
        }

        public async Task HandleAsync(PurchaseCreatedEvent broadcasted)
        {
            // Ommitted lines for brevity.
        }
    }

I am not sure if I have configured events and queues below as show below

var provider = app.ApplicationServices;
var registration = provider.ConfigureEvents();
registration.Register<PurchaseCreatedEvent>()
    .Subscribe<PurchaseCreatedListener>();
provider.ConfigureQueue().LogQueuedTaskProgress(provider.GetService<ILogger<IQueue>>())
    .OnError(e => { // Ommited for brevity });

I hope I have provide enough information.

[jamesmh]

Awesome. I forgot to ask (sorry!) - what version of Coravel are you using?

[khabubu]

Version 2.3.1

[jamesmh]

Great. I'll try to get to this in the new couple days.

[jamesmh]

Quick question: Did you register your listeners with AddTransient or AddScoped?

[khabubu]

No I didn't register with either. I think that is my issue. Let me try registering it. Ohh is this the proper way to register a listener

services.AddTransient<IListener<PurchaseCreatedEvent>, PurchaseCreatedListener>();

I had registered the listeners and events as follow

var provider = app.ApplicationServices;
var registration = provider.ConfigureEvents();
registration.Register<PurchaseCreatedEvent>()
                .Subscribe<PurchaseCreatedListener>();

[jamesmh]

You can just do services.AddTransient<PurchaseCreatedListener>() - does that fix your issues?

[khabubu]

Yes it does. Thank you very much.
PS : I feel stupid now. Thanks again

[jamesmh]

hahaha! Don't worry about it. Glad everything is working now 👍
