Python 谷歌云功能使用pubsub消息启动其他GCF，以'；状态：连接错误'；

情况：

• 我有两个google云函数，我们称它们为gcf composer和gcf action
• 我有一个70000个我想要执行gcf操作的唯一DICT的列表
• 我在所有dict上使用gcf composer循环，并将每个dict的消息发布到包含dict作为有效负载的gcf操作主题
• 我需要gcf编写器，因为直接为所有DICT运行gcf操作需要9分钟以上的时间
• 我使用googlecloudscheduler启动gcf编写器

问题
在云上启动gcf composer时，x秒后，它将停止并返回以下内容：

这些是4次单独尝试的结果

为什么它会给我“已完成状态：'连接错误'”，我该如何解决它
当我在本地运行此功能，以便向主题发送消息时，它会起作用。

2个问题：PubSubConnection的功能是什么？在连接错误消息出现前的前几秒钟内，您是否在pubSub主题中发布了消息？@guillaumeblaquiere添加了PubSubConnection函数。是的，因此在连接错误发生之前，gcf操作get至少被调用了200-300次。
