Firebase 和 Google 跟踪代码管理器：<FIRAnalytics/WARNING> 尝试记录 nil 事件

Question

我在 cocoapods 上集成了 Firebase 和 GTM：

pod 'Firebase/Core'
pod 'GoogleTagManager', '~> 5.0'

所用版本的 Podfile.lock ：

• Firebase/核心 (3.12.0)：
  • FirebaseAnalytics (= 3.6.0)
  • FirebaseCore (= 3.4.7)
• FirebaseAnalytics (3.6.0)：
  • FirebaseCore (~> 3.4)
  • FirebaseInstanceID (~> 1.0)
  • GoogleInterchangeUtilities (~> 1.2)
  • GoogleSymbolUtilities (~> 1.1)
  • GoogleToolboxForMac/NSData+zlib (~> 2.1)
• FirebaseCore (3.4.7)：
  • GoogleInterchangeUtilities (~> 1.2)
  • GoogleSymbolUtilities (~> 1.1)
  • GoogleToolboxForMac/NSData+zlib (~> 2.1)
• FirebaseInstanceID (1.0.8)
• GoogleAnalytics (3.17.0)
• GoogleInterchangeUtilities (1.2.2)：
  • GoogleSymbolUtilities (~> 1.1)
• GoogleSymbolUtilities (1.1.2)
• GoogleTagManager (5.0.8)：
  • FirebaseAnalytics (~> 3.0)
  • GoogleAnalytics (~> 3.0)
  • GoogleUtilities (~> 1.3.0)
• GoogleToolboxForMac/Defines (2.1.1)
• GoogleToolboxForMac/NSData+zlib (2.1.1)：
  • GoogleToolboxForMac/Defines (= 2.1.1)
• 谷歌实用程序 (1.3.2)：
  • GoogleSymbolUtilities (~> 1.1)

并按照文档中的步骤进行集成，但我收到以下警告：

 GoogleTagManager info: Processing logged event: (null) with parameters: (null)
 <FIRAnalytics/WARNING> Attempted to log nil event

从应用开始的完整日志：

编辑

我从配置文件中删除了“.json”扩展名。日志说：

GoogleTagManager warning: No default container found. Container needs to be added to a container folder and added to the target.
Configuration was not found in database. The configuration will be fetched from the network when necessary
Firebase Analytics is ready to receive events
Firebase Analytics enabled
Fetching configuration from the server

Successfully parsed a configuration. Version: 1484056.........
Measurement data sent to network

有什么想法吗？？？

但是错误消失了？？？

任何想法

将 Pod 升级到最新版本：

• Firebase/核心 (3.14.0)：
  • FirebaseAnalytics (= 3.7.0)
  • FirebaseCore (= 3.5.1)
• FirebaseAnalytics (3.7.0)：
  • FirebaseCore (~> 3.5)
  • FirebaseInstanceID (~> 1.0)
  • GoogleToolboxForMac/NSData+zlib (~> 2.1)
• FirebaseCore (3.5.1)：
  • GoogleToolboxForMac/NSData+zlib (~> 2.1)
• FirebaseInstanceID (1.0.9)
• GoogleAnalytics (3.17.0)
• GoogleSymbolUtilities (1.1.2)
• GoogleTagManager (5.0.8)：
  • FirebaseAnalytics (~> 3.0)
  • GoogleAnalytics (~> 3.0)
  • GoogleUtilities (~> 1.3.0)
• GoogleToolboxForMac/Defines (2.1.1)
• GoogleToolboxForMac/NSData+zlib (2.1.1)：
  • GoogleToolboxForMac/Defines (= 2.1.1)
• 谷歌实用程序 (1.3.2)：
  • GoogleSymbolUtilities (~> 1.1)

但仍然收到保留事件错误：

2017-03-02 11:00:17.854 <Error> [Firebase/Analytics][I-ACS013006] Event name is reserved. Ignoring event: user_engagement
2017-03-02 11:00:17.854 GoogleTagManager info: Processing logged event: (null) with parameters: (null)

有趣的是 Firebase 忽略了以下事件：

• 由 Firebase 或 GTM 保留
• 我没有发送

:(

Answer 1

在我的情况下，问题是因为以错误的方式包含文件。只要确保正确包含容器文件夹即可。提示：项目导航器中的文件夹图标颜色应为蓝色。

Answer 2

当您删除 json 扩展时，Google 跟踪代码管理器无法找到任何容器，并且不会下载容器。您可以从发布屏幕或容器的版本页面下载容器。

自动记录的事件“_s”被忽略，因为 Firebase Analytics 已经记录了该事件，并且 Google 跟踪代码管理器不会修改自动事件。您可以使用“_s”事件触发其他代码，或触发自定义 Firebase Analytics 代码。

要跟踪有关空事件名称的其他警告，我会在您的代码中搜索任何使用未初始化变量的 logEvent 调用。
