Masstransit, saga resource not being created - masstransit

Question

I have two services, one acts as a consumer, the other as a producer. Following are my configurations for each of them.
Producer config
services
.AddSingleton(KebabCaseEndpointNameFormatter.Instance);
services
.AddMassTransit(config =>
{
config.AddBus(serviceProvider =>
Bus.Factory.CreateUsingRabbitMq(config =>
{
config.Host(new Uri("amqp://admin:pass#localhost"));
}));
})
.AddMassTransitHostedService();
Consumer config
services
.AddSingleton(KebabCaseEndpointNameFormatter.Instance);
services
.AddMassTransit(config =>
{
config.AddSagaStateMachine<OrderStateMachine, OrderState>()
.RedisRepository();
config.AddBus(serviceProvider =>
Bus.Factory.CreateUsingRabbitMq(config =>
{
config.Host(new Uri("amqp://admin:pass#localhost"));
config.ReceiveEndpoint("service-5-queue", endpointConfig =>
{
endpointConfig.Consumer<SubmitOrderCommand>();
});
}));
})
.AddMassTransitHostedService();
Following some online tutorial, when the app launches, then I should see some queues and exchanges being created, one of which should be some 'order-state' exchange and queue. Unfortunatly not the case.
Anyone using masstransit having some idea why is this the case ?
The logs

Sending some message triggers the consumer, but the saga doesn't get trigger at any moment, nor it is invoked during some initialization steps or something.

Answer 1

You should remove the explicit receive endpoint configuration, and call ConfigureEndpoints. This will create the endpoint for the saga.
services
.AddMassTransit(config =>
{
config.AddSagaStateMachine<OrderStateMachine, OrderState>()
.RedisRepository();
config.UsingRabbitMq((context,cfg) =>
{
cfg.Host(new Uri("amqp://admin:pass#localhost"));
cfg.ConfigureEndpoints(context);
});
})
.AddMassTransitHostedService();
