Unsupported object CPInformationTemplate - swift

Question

The error I am getting is the following.
Thread 1: "Unsupported object <CPInformationTemplate: 0x6000012de010> <identifier: 3444D3F1-ECFF-4953-B543-459286E11371, userInfo: (null), tabTitle: (null), tabImage: (null), showsTabBadge: 0> passed to setRootTemplate:animated:completion:. Allowed classes: {(\n CPTabBarTemplate,\n CPListTemplate,\n CPGridTemplate,\n CPAlertTemplate,\n CPVoiceControlTemplate,\n CPNowPlayingTemplate\n)}"
All I am trying to do so, far is show a simple basic text. - I am following https://adapptor.com.au/blog/enhance-existing-apps-with-carplay
Any suggestions would be helpful.

class CarPlaySceneDelegate: UIResponder, CPTemplateApplicationSceneDelegate {

let screen = CPInformationTemplate(title: "Root", layout: .leading, items: [CPInformationItem(title: "Hello", detail: "CarPlay")], actions: [])
interfaceController.setRootTemplate(screen, animated: true, completion: { _,_ in
// Do nothing
})
} else {
// Fallback on earlier versions
}
}

Which entitlements you have defined in your project? The templates availability depends on defined app entitlements.
Usage of the unsupported template (CPInformationTemplate) cause your error.
For example from documentation:
You can’t use CPInformationTemplate in apps with the audio
entitlement.
