Describe the bug

When calling the getExpand method with parameters from the cat videos example, an IllegalArgumentException (log output below) is thrown.

Code

@Component
public class StartupApplicationListenerExample implements ApplicationListener<ContextRefreshedEvent> {

    private static Logger logger = LoggerFactory.getLogger(StartupApplicationListenerExample.class);

    private final String ketoApiUrl;

    public StartupApplicationListenerExample(@Value("${keto.api.url}") String ketoApiUrl) {
        this.ketoApiUrl = ketoApiUrl;
    }

     @Override
     public void onApplicationEvent(ContextRefreshedEvent event) {

        // Make a call to Keto and expand a tree with all subjects that can view /cats/1.mp4
        ReadApi api = new ReadApi();
        api.setCustomBaseUrl(ketoApiUrl);

        String namespace = "videos";
        String _object = "/cats/1.mp4";
        String relation = "view";
        String subjectId = "*";
        String subjectSetNamespace = null;
        String subjectSetObject = null;
        String subjectSetRelation = null;
        Long maxDepth = null;
        try {

            ExpandTree responseExpand = api.getExpand(namespace, _object, relation, 3L);
            logger.info("Response Expand: {}", responseExpand);
        } catch (ApiException e) {
            logger.info("Response body: {}", e.getResponseBody());
            throw new IllegalStateException("Could not perform API request", e);
        }
    }
}

Relevant line

ExpandTree responseExpand = api.getExpand(namespace, _object, relation, 3L);

Reproducing the bug

Follow the cat video quickstart example here: https://www.ory.sh/docs/keto/quickstart
Call ReadApi.getExpand("videos", "/cats/1.mp4", "view", 3L);
java.lang.IllegalArgumentException: Unexpected value 'union'

Version

Java Client for Ory Keto 0.8.0-alpha.1 (https://search.maven.org/artifact/sh.ory.keto/keto-client/0.8.0-alpha.1/jar)

On which operating system are you observing this issue?

Windows

In which environment are you deploying?

No response

Additional Context

ReadApi.getCheck does work from the same class. Everything is set up and running properly.
When changing the max depth to 1L, the type of unexpected value changes from union to leaf.
When setting max depth to 0L no exception is thrown. Instead the expected empty Expand Tree is returned.
The IllegalArgumentException is thrown at ExpandTree.java > public static TypeEnum fromValue(String value) (line 70-77)

    public static TypeEnum fromValue(String value) {
      for (TypeEnum b : TypeEnum.values()) {
        if (b.value.equals(value)) {
          return b;
        }
      }
      throw new IllegalArgumentException("Unexpected value '" + value + "'");
    }
