The callback execution failed in my test:
The ECS task did not send a callback within the timeout period
The ECS task log has the following:
[CALLBACK] ERROR: An error occurred (TaskTimedOut) when calling the SendTaskSuccess operation: Task Timed Out: 'Provided task does not exist anymore'
[CALLBACK] Failed to send callback: An error occurred (TaskTimedOut) when calling the SendTaskFailure operation: Task Timed Out: 'Provided task does not exist anymore'
