Hi,
In 4.4 we use dead letter queues for RabbitMQ, But in 5.0 we introduced the inbox outbox pattern, so we no longer use the dead letter queue.
Sorry RabbitMQ does not support update queues, you may need to delete existing queues.
See https://dev.to/ottonova/how-and-why-we-updated-rabbitmq-queues-on-production-2h76

If you don't want to delete the queue.
You can try:
[Dependency(ReplaceServices = true)] public class MyRabbitMqMessageConsumer : RabbitMqMessageConsumer { public MyRabbitMqMessageConsumer(IConnectionPool connectionPool, AbpAsyncTimer timer, IExceptionNotifier exceptionNotifier) : base(connectionPool, timer, exceptionNotifier) { } protected override Task TryCreateChannelAsync() { Queue.Arguments["x-dead-letter-exchange"] = Exchange.ExchangeName+"_dead_letter";; Queue.Arguments["x-dead-letter-routing-key"] = Queue.QueueName+"_dead_letter"; return base.TryCreateChannelAsync(); } } [Dependency(ReplaceServices = true)] [ExposeServices(typeof(IRabbitMqMessageConsumerFactory))] public class MyRabbitMqMessageConsumerFactory : IRabbitMqMessageConsumerFactory, ISingletonDependency, IDisposable { protected IServiceScope ServiceScope { get; } public MyRabbitMqMessageConsumerFactory(IServiceScopeFactory serviceScopeFactory) { ServiceScope = serviceScopeFactory.CreateScope(); } public IRabbitMqMessageConsumer Create( ExchangeDeclareConfiguration exchange, QueueDeclareConfiguration queue, string connectionName = null) { var consumer = ServiceScope.ServiceProvider.GetRequiredService<MyRabbitMqMessageConsumer>(); consumer.Initialize(exchange, queue, connectionName); return consumer; } public void Dispose() { ServiceScope?.Dispose(); } }
