Currently, I’m attempting to move from aws sdk to MassTransit. And I have a big issue with connecting to the SQS/SNS.
Our infrastructure team created sqs/sns using a terraform script. And we (as developers and application) cannot change (in any way) it since the infrastructure is managed by a separate team and another aws account/role.

We’re using MassTransit 8.0 (the newest version)

Basically we have:
queue:

name: bci-name-dev-aim-name

encryption: SSE-SQS

Where we have SNS subscription:

arn:aws:sqs:us-west-2::bci-name-dev-aim-name to topic: bci-name-dev-aim-name-topic (protocol SQS)

As a topic

name: bci-name-dev-aim-name-topic

encryption: default one (alias/aws/sns)

My producer configuration looks:

services.AddMassTransit(cfg =>
                {
                    cfg.UsingAmazonSqs((context, bus) =>
                    {
                        bus.UseMessageScheduler(schedulerEndpoint);
            
                        bus.Host("us-west-2", h => {}); //using env Variables

                        bus.Message<PublicationMessage>(x =>
                        {
                            x.SetEntityName("bci-name-dev-aim-name-topic");
                        });
                        
                        bus.ConfigureEndpoints(context);
                    });
                });

My consument:

services.AddMassTransit(cfg =>
                {
                    cfg.AddConsumer<PublicationMessageConsumer>();
        
                    cfg.UsingAmazonSqs((context, bus) =>
                    {                            
                        bus.Host("us-west-2", h => {});

                        
                        bus.PublishTopology.TopicAttributes.Add(QueueAttributeName.KmsMasterKeyId, "alias/aws/sns");

                        bus.ReceiveEndpoint("bci-name-dev-aim-name", ec =>  //queue name
                        {
                            // disable the default topic binding
                            ec.ConfigureConsumeTopology = false;
                            ec.QueueAttributes.Add(QueueAttributeName.KmsMasterKeyId, "alias/aws/sqs");
                            
                            ec.Subscribe("bci-name-dev-aim-name-topic");    //topic name
                            
                            ec.ConfigureConsumer<PublicationMessageConsumer>(context);
                        });
                        
                        bus.ConfigureEndpoints(context);
                    });
                });

After starting the application (console app). Producer is reports (during starting app):

  info: MassTransit[0]
  Bus started: amazonsqs://us-west-2/

But when I tried to start consumer I got:

  info: MassTransit[0]
  Configured endpoint bci-name-dev-aim-name, Consumer: Consumer.PublicationMessageConsumer

(thats’s the only log so no bus started log etc)

When I stop the consumer I receive:

  warn: MassTransit[0]
  Failed to stop bus: amazonsqs://us-west-2/BKOWALCZYKW1_Consumer_bus_kotoyynbyybfbeanbdpf9sykno?durable=false&autodelete=true (Not Started)

Can you advise?

++++++ EDITED:

I tried to adapt to suggestions from @Chris Patterson. And currently my configuration looks:

Producer:

services.AddMassTransit(cfg =>
                {
                    cfg.UsingAmazonSqs((context, bus) =>
                    {
                        bus.UseMessageScheduler(schedulerEndpoint);
            
                        bus.Host("us-west-2", h => {}); //using env Variables

                        bus.Message<PublicationMessage>(x =>
                        {
                            x.SetEntityName("bci-name-dev-aim-name-topic");
                        });
                        
                        bus.ConfigureEndpoints(context);
                    });
                });

Consumer:

services.AddMassTransit(cfg =>
                {
                    cfg.AddConsumer<PublicationMessageConsumer>();
        
                    cfg.UsingAmazonSqs((context, bus) =>
                    {                            
                        bus.Host("us-west-2", h => {});

                        bus.ReceiveEndpoint("bci-name-dev-aim-name", ec =>  //queue name
                        {
                            // disable the default topic binding
                            ec.ConfigureConsumeTopology = false;
                         
                            ec.ConfigureConsumer<PublicationMessageConsumer>(context);
                        });
                        
                        bus.ConfigureEndpoints(context);
                    });
                });

And It looks like the consumer reported: “Bus started: amazonsqs://us-west-2/”.
So it works
