我的Firebase可调用函数需要在传递无效值时通知客户端。 根据文档，应该使用functions.https.httpserror-

      if (!condition) {
        throw new functions.https.HttpsError(
          'invalid-argument',
          'Cheating will incur ban'
        );
      }

添加客户端代码来调用文档中给出的函数会导致应用程序崩溃。

    fun addPlayTime(playTime: Int): Task<String> {
        val data = hashMapOf(
            "playTime" to playTime
        )
        return functions
            .getHttpsCallable("addPlayTime")
            .call(data)
            .continueWith { task ->
                val result = task.result?.data as String
                result
            }
    }

            viewModel.addPlayTime(10000)
                .addOnCompleteListener { task ->
                    Timber.d("API response: ${task.result}")
                    if (!task.isSuccessful) {
                        val e = task.exception
                        if (e is FirebaseFunctionsException) {
                            val code = e.code
                            val details = e.details
                            Timber.d("API call failed: $details")
                        }
                    }
                }

我能在logcat中看到错误。 我如何处理这个异常而不让我的应用程序崩溃？ 将上面的代码包装在try-catch中没有任何帮助。
