  weight: 123,
};
```

## Properties

- `stateMachineVersionArn`: string (required) — The Amazon Resource Name (ARN) that identifies one or two state machine versions defined in the routing configuration.

  If you specify the ARN of a second version, it must belong to the same state machine as the first version.

  The sum of the weights in the routing configuration must be equal to 100.
