title: Cloudwatch failedinvocation error no logs available
body: <p>I have set up a Cloudwatch rule event where an ECS task definition is started when a previous task definition is completed. </p>
  
  <p>I can see the event triggers the task definition however it fails.</p>
  
  <p>The only visibility of this failure is in the rule metrics, where I see the metric failedinnvocations.</p>
  
  <p>Question, are there any logs to see why the trigger failed?</p>
  
  <p>I can manually set up the rule via the management console and everything works fine. </p>
  
  <p>The error occurs when I set up the rule via a cloudformation template.</p>
  
  <p>I have compared the two rules and both are identical, except the role. However, both roles have the same permissions.</p>
