ModernUI Screen throwing View not found error

I’ve been extolling the virtues of the Modern UI to my colleagues, especially how straight forward it is to code. Unfortunately I’ve found myself stuck on a screen where I simply cannot see the issue. The classic UI version of the screen is working fine, but I cannot get the Modern UI screen to work. The environment is 2025R2.

The screen is supported by the following DAC

using System;
using PX.Data;
using PX.Objects.CS;

namespace SoImportDemo
{
	[PXCacheName(Helpers.Messages.ZZSoImportSetup)]
	[PXPrimaryGraph(typeof(ZZSoImportSetupMaint))]
	public class ZZSoImportSetup : PXBqlTable, IBqlTable
	{
		#region NumberingID
		[PXDBString(10, IsUnicode = true, InputMask = "")]
        [PXSelector(typeof(Numbering.numberingID),
            DescriptionField = typeof(Numbering.descr))]
        [PXUIField(DisplayName = "Numbering Sequence")]
		[PXDefault("SOIMPORT")]
        public virtual string NumberingID { get; set; }
		public abstract class numberingID : PX.Data.BQL.BqlString.Field<numberingID> { }
		#endregion

		#region ClientID
		[PXDBString(50, IsUnicode = true, InputMask = "")]
		[PXUIField(DisplayName = "Client ID")]
		public virtual string ClientID { get; set; }
		public abstract class clientID : PX.Data.BQL.BqlString.Field<clientID> { }
		#endregion

		#region TenantID
		[PXDBString(50, IsUnicode = true, InputMask = "")]
		[PXUIField(DisplayName = "Tenant ID")]
		public virtual string TenantID { get; set; }
		public abstract class tenantID : PX.Data.BQL.BqlString.Field<tenantID> { }
		#endregion

		#region Secret
		[PXDBString(100, IsUnicode = true, InputMask = "")]
		[PXUIField(DisplayName = "Secret")]
		public virtual string Secret { get; set; }
		public abstract class secret : PX.Data.BQL.BqlString.Field<secret> { }
		#endregion

		#region Scope
		[PXDBString(100, IsUnicode = true, InputMask = "")]
		[PXUIField(DisplayName = "Scope")]
		public virtual string Scope { get; set; }
		public abstract class scope : PX.Data.BQL.BqlString.Field<scope> { }
		#endregion

		/// system field removed for brevity ///
	}
}

and Graph

using System;
using PX.Data;
using PX.Data.BQL.Fluent;

namespace SoImportDemo
{
	public class ZZSoImportSetupMaint : PXGraph<ZZSoImportSetupMaint>
	{

		public PXSave<ZZSoImportSetup> Save = null;
		public PXCancel<ZZSoImportSetup> Cancel = null;

		public SelectFrom<ZZSoImportSetup>.View SetupView = null;

    }
}

And here is the Tyepscript and HTML for the screen
 

import { createSingle, graphInfo, PXView, PXScreen, PXFieldState, viewInfo } from "client-controls";

@graphInfo({
    graphType: "SoImportDemo.ZZSoImportSetupMaint",
    primaryView: "SetupView",
})
export class ZZ101000 extends PXScreen {
    @viewInfo({ containerName: "SO Import Preferences" })
    SetupView = createSingle(ZZSoImportSetup);

}

export class ZZSoImportSetup extends PXView {
    NumberingID: PXFieldState;
    ClientID: PXFieldState;
    TenantID: PXFieldState;
    Secret: PXFieldState;
    Scope: PXFieldState;
}

<template>
	<qp-template id="form-Setup" name="7-10-7" class="equal-height">

		<qp-fieldset id="columnA-Setup" view.bind="SetupView" slot="A">
			<field name="NumberingID"></field>
		</qp-fieldset>

		<qp-fieldset id="columnB-Setup" view.bind="SetupView" slot="B">
			<field name="ClientID"></field>
			<field name="TenantID"></field>
			<field name="Secret"></field>
			<field name="Scope"></field>
		</qp-fieldset>		

	</qp-template>
</template>

When the screen is opened the following error is show in the trace

I cannot for the life of me see what the issue is. The view names are correct the field names are all correct as far as I can see. Any help would be greatly appriciated.
