DeadLetterConfig
The object used to specify the Amazon Simple Queue Service (Amazon SQS) queue where EventBridge sends events after a failed target invocation. Invocation can fail, for example, when sending an event to a state machine that doesn’t exist, or insufficient permissions to invoke the state machine. For more information, see Event retry policy and using dead-letter queues in the Amazon EventBridge User Guide.
