## Example

```ts
const jsonata = sfn.Pass.jsonata(this, 'JSONata');
const jsonPath = sfn.Pass.jsonPath(this, 'JSONPath');
const definition = jsonata.next(jsonPath);

new sfn.StateMachine(this, 'MixedStateMachine', {
  // queryLanguage: sfn.QueryLanguage.JSON_PATH, // default
  definitionBody: sfn.DefinitionBody.fromChainable(definition),
});

// This throws an error. If JSONata is specified at the top level, JSONPath cannot be used in the state machine definition.
new sfn.StateMachine(this, 'JSONataOnlyStateMachine', {
  queryLanguage: sfn.QueryLanguage.JSONATA,
  definitionBody: sfn.DefinitionBody.fromChainable(definition),
});
```
