超过AWSLogs资源限制-无服务器`cloudwatchLog`事件

Question

我正在尝试将cloudwatchLog事件添加到我的lambda函数中，并且遇到意外错误。该错误消息不是很描述。有人知道发生了什么吗？

配置：

functions:
  helloWorld:
    handler: dist/handlers/index.helloWorld
    events:
      - cloudwatchLog:
          logGroup: '/aws/lambda/serverless-test-package-4-dev-supWorld'

错误信息：

Answer 1

问题在于，已经有一个Lambda订阅了CloudWatchLog事件。AWS将每个CloudWatch Log Group限制为最多一个订阅，如本文档最后一行所指定。
