Running CloudMapper regularly to audit your environment

[LaeeqAL]

Ran the command in terminal as root: aws events put-events --entries '[{"Source":"cloudmapper","DetailType":"start","Detail":"{}"}]'
Returned:
{
"FailedEntryCount": 0,
"Entries": [
{
"EventId": "<ID of the event (not adding it for security purposes)>"
}
]
}

How do I rectify this? Also are there any other ways to test this way of using the cloudmapper to send audits to a slack channel?
