-###### Note
-
-Unhandled errors in Lambda runtimes were historically reported only as `Lambda.Unknown`. In newer runtimes, timeouts are reported as `Sandbox.Timedout` in the error output.When Lambda exceeds the maximum number of invocations, the reported error will be `Lambda.TooManyRequestsException`.Match on `Lambda.Unknown`, `Sandbox.Timedout`, and `States.TaskFailed` to handle possible errors. You can also use `States.ALL`, but it must be alone and at the end of the list.For more information about Lambda `Handled` and `Unhandled` errors, see `FunctionError` in the [AWS Lambda Developer Guide](https://docs.aws.amazon.com/lambda/latest/dg/API_Invoke.html#API_Invoke_ResponseSyntax).  | October 17, 2017
