iOS Intents动态参数加载失败且handle方法未调用问题

在苹果快捷指令App中，点击快捷指令内动态提供的参数时，弹出**‘An unknown error occurred.’**错误，且handle(intent: TestIntent) async -> TestIntentResponse方法未被调用。我已实现Xcode提供并生成的Handling协议，相关代码如下：

class SiriKitAppClosingIntentHandler: NSObject, LogAppClosingIntentHandling {
    func provideAppOptionsCollection(for intent: LogAppClosingIntent, searchTerm: String?) async throws -> INObjectCollection<SiriKitIntentAppName> {
        let appOptionsCollection = AppName.appOptionsCollection
        if let searchTerm = searchTerm, !searchTerm.isEmpty {
            return INObjectCollection(items: appOptionsCollection.filter({ $0.displayString.contains(searchTerm) }))
        } else {
            return INObjectCollection(items: appOptionsCollection)
        }
    }
    
    func handle(intent: LogAppClosingIntent) async -> LogAppClosingIntentResponse {
        print(" closing intent \(intent) \(#file) \(#line)")
        return LogAppClosingIntentResponse(code: .success, userActivity: nil)
    }
}
