-[FBLPromise HTTPBody]:非初始启动时发送到实例0x600001afa700的无法识别的选择器出错。谷歌翻译MLKit

我正在尝试将Google MLKit Translate添加到我的SwiftUI项目中。我已经在通过SPM使用firebase,只有在首次启动后才会出现以下错误: -[FBLPromise HTTPBody]: unrecognized selector sent to instance 0x600001afa700

这是我的代码:

程序委托

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        ...
        FirebaseApp.configure()
        ...
        let spanishRemoteTranslator = TranslateRemoteModel.translateRemoteModel(language: .spanish)
        if ModelManager.modelManager().isModelDownloaded(spanishRemoteTranslator) {
            print("Spanish Translator Downloaded")
        }else {
            print("Downloading Spanish Translator")
            
            ModelManager.modelManager().download(spanishRemoteTranslator, conditions: ModelDownloadConditions(allowsCellularAccess: true, allowsBackgroundDownloading: true))
        }
        return true
}

然后我这样称呼它:

if ModelManager.modelManager().isModelDownloaded(spanishModel) {
    Translator.translator(options: englishSpanishTranslator).translate(buis.name!) { translatedText, error in
        if error == nil {
            if let translatedText = translatedText {
                name = translatedText
            }else {
                print("error = \(error)")
            }
        }else {
            print("error = \(error)")
        }
    }
}else {
    print("error = Spanish not downloaded")
}

我也尝试过使用内置的FirebaseMLKitDownload,但它没有翻译器。怎么回事?
