Cloudwatch failedinvocation 错误没有可用的日志 [英] Cloudwatch failedinvocation error no logs available

问题描述

我设置了一个 Cloudwatch 规则事件，其中一个 ECS 任务定义在上一个任务定义完成时启动.

I have set up a Cloudwatch rule event where an ECS task definition is started when a previous task definition is completed.

我可以看到事件触发了任务定义，但它失败了.

I can see the event triggers the task definition however it fails.

此故障的唯一可见性是在规则指标中，我在其中看到了指标 failedinnvocations.

The only visibility of this failure is in the rule metrics, where I see the metric failedinnvocations.

问题，是否有任何日志可以查看触发器失败的原因?

Question, are there any logs to see why the trigger failed?

我可以通过管理控制台手动设置规则，一切正常.

I can manually set up the rule via the management console and everything works fine.

当我通过 cloudformation 模板设置规则时出现错误.

The error occurs when I set up the rule via a cloudformation template.

我已经比较了这两个规则，除了角色之外，两者都是相同的.但是，这两个角色具有相同的权限.

I have compared the two rules and both are identical, except the role. However, both roles have the same permissions.

推荐答案

如果规则已成功触发，但目标上的调用失败，您应该在 AWS CloudTrail 内的 Event History 中看到 API 调用的跟踪查看 errorCode 和 errorMessage 属性:

If the rule has been successfully triggered, but the invocation on the target failed, you should see a trace of the API call in the Event History inside the AWS CloudTrail looking at the errorCode and errorMessage properties:

{
   [..]
   "errorCode": "InvalidInputException",
   "errorMessage": "Artifacts type is required",
   [..]
}
