title: Cron not valid?
body: <p>I'm trying to deploy an EventBridge rule in Terraform with the following cron expression:</p>
  <pre><code>schedule_expression = &quot;cron (5 5 * * ? *)&quot;
  </code></pre>
  <p>Trying to apply the plan however, throws</p>
  <pre><code>Error: error creating EventBridge Rule (dev-cron): 
  ValidationException: Parameter ScheduleExpression is not valid.
  status code: 400, request id: xxx
  </code></pre>
  <p>I have tried a cron generator, followed AWS docs on crons, and tried different cros, all throwing the same error. What am I missing here?</p>
