Putting an event on an nonexistent EventBridge event bus returns a success

[gemyago]

Describe the bug

Attempting to publish the event to a non existing event bus returns a successful response (e.g FailedEntryCount=0 and no entries with errors)

This is a continuation of the aws/aws-sdk#186.

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

Attempt to publish the event to non existing event bus must return error response for corresponding entries: FailedEntryCount should correspond to number of failures and Entries should indicate error details.

Current Behavior

No errors in response

Reproduction Steps

Pub message to non existing event bus:

 aws events put-events --entries '[
  {
    "Source": "my-source",
    "DetailType": "message",
    "Detail": "{\"id\": \"123\", \"name\": \"123\"}",
    "EventBusName": "not-existing-event-bus-AS31Q3131BB31134"
  }
]'

The response is:

{
    "FailedEntryCount": 0,
    "Entries": [
        {
            "EventId": "af4e8101-0d66-bba4-4f33-7f0af2c13327"
        }
    ]
}
