MassTransit - MessageLockExpiredException - Longer executing message fails on completion

Question

I have a MassTransit Consumer that should on average complete its messages in 15-20 minutes.

I am using Azure.ServiceBus.Core transport.

The message will successfully operate through all configured business logic, but the message instead faults on a MassTransit.MessageLockExpiredException after the message completes.

I've tried setting MaxAutoRenewDuration and LockDuration

                x.UsingAzureServiceBus((context, cfg) =>
                {
                    cfg.Host(hostContext.Configuration["AzureServiceBus_ConnectionString"]);
                    cfg.UseConsumeFilter(typeof(ConsumeContextFilter<>), context);
                    cfg.ConfigureEndpoints(context);
                    cfg.MaxAutoRenewDuration = TimeSpan.FromMinutes(30);
                    cfg.LockDuration = TimeSpan.FromMinutes(30);
                });

Answer 1

You need to configure the properties on the receive endpoint, not the bus.

x.AddConfigureEndpointsCallback((context, name, cfg) => 
{
    if(cfg is IServiceBusReceiveEndpointConfigurator sb)
    {
        sb.LockDuration = TimeSpan.FromMinutes(5);
        sb.MaxAutoRenewDuration = TimeSpan.FromMinutes(30);
    });
});
