24.3 Build an Application: Step-by-Step #10 - Could not display interface

Before dragging and dropping a Design Library item

Afterwards

a!formLayout(
  label: "New Maintenance Request",
  contents: {
    a!sectionLayout(
      contents: {}
    ),
    a!sectionLayout(
      label: "Vehicle Details",
      contents: {
        rule!W2735SA_VehicleDetailsView(
          vehicle: ri!maintenance['recordType!{6909d85e-e650-4ce3-90f0-6447c16264e8}W2735SA Maintenance.relationships.{864e027a-211d-462d-a62a-5a6648aaab20}vehicle'],
          approvaldecision: null
        )
      }
    )
  },
  buttons: a!buttonLayout(
    primaryButtons: {
      a!buttonWidget(
        label: "Submit",
        submit: true,
        style: "SOLID"
      )
    },
    secondaryButtons: {
      a!buttonWidget(
        label: "Cancel",
        value: true,
        saveInto: ri!cancel,
        submit: true,
        style: "OUTLINE",
        validate: false
      )
    }
  )
)

When I drag and drop my W#SA_VehicleDetailsView from my Design Library and format it and hit Ok I get this error.  I went back to the original steps for creating the Design to verify it was all correct and it checked fine.
