Mass Action button gives IDacDescriptorProvider error

I’m trying to add a button to the Sales Orders list - S301000PL. I’ve defined the action in a Graph Extension and see it available as a ‘Graph Action’ on the Customization Project screen (SCREENS → SO301000 > Actions). The action is available on the drop-down panel on SO3010PL alongside the standard options.

Clicking the action gives the error “At least one record hasn’t been processed”

Trace gives:

Autofac.Core.Registration.ComponentNotRegisteredException

The requested service 'PX.Data.DacDescriptorGeneration.IDacDescriptorProvider' has not been registered. To avoid this exception, either register a component to provide the service, check for service registration using IsRegistered(), or use the ResolveOptional() method to resolve an optional dependency

I have set a breakpoint within the action handler, but it doesn’t get hit.

The action is defined by this code:

    public class SOOrderEntry_Extension : PXGraphExtension<PX.Objects.SO.SOOrderEntry>
    {
        public override void Initialize()
        {
            HaveCalledCustomer.IsMass = true;
        }

        public PXAction<SOOrder> HaveCalledCustomer;
        [PXProcessButton(DisplayOnMainToolbar = true, CommitChanges = true)]
        [PXUIField(DisplayName = Messages.Called, MapEnableRights = PXCacheRights.Update, MapViewRights = PXCacheRights.Select, Visible = true, Enabled = true, IsDirty = true)]
        public virtual IEnumerable haveCalledCustomer(PXAdapter adapter)
        {
            bool isMassProcess = adapter.MassProcess;

            List<SOOrder> orderList = new List<SOOrder>();
//omitted for brevity

            return orderList;
        }
 

What might I have missed? How can I fix this?
