title: AWS Lambda: error creating the event source mapping: Configuration is ambiguously defined
body: <blockquote>
    <p>There was an error creating the event source mapping: Configuration is ambiguously defined. Cannot have overlapping suffixes in two rules if the prefixes are overlapping for the same event type.</p>
  </blockquote>
  
  <p>I created an event earlier from the GUI console 6-7 days ago and it was working fine. The next day the event just missing, i cant see it anymore at the Lambda console GUI. But every S3 objects still seems triggering the lambda function not a problem.   If i cant see, it is not good; So i deleted the Lambda function, waited for 5-10 seconds before creating another new function. And now, i receive the same above when i try to create the event sources like this:

  <p>When i click "Submit" the event sources tab says "You do not have any event sources for this function", Lambda does not get triggered; it means the entire application flow is now broken  :(</p>
  
  <p>The problem is almost the same as: "<a href="https://forums.aws.amazon.com/thread.jspa?messageID=670712" rel="noreferrer">https://forums.aws.amazon.com/thread.jspa?messageID=670712</a>" But somehow i cant reply to that thread, so i created a new thread here instead. anyone encounter this issue?</p>
  
  <p>In fact, i try to response to the existing AWS forum thread: <a href="https://forums.aws.amazon.com/thread.jspa?messageID=670712&amp;#670712" rel="noreferrer">https://forums.aws.amazon.com/thread.jspa?messageID=670712&amp;#670712</a>
