I have followed the [documentation][1] and I cannot get FLE to work in my SpringBoot Java application..

Whenever I attempt to use an @Encrypted annotation, it responds with the following Exception:

Request processing failed: java.lang.IllegalArgumentException: cryptoManager needed to encrypt/decrypt but it is null. Override needed for cryptoManager() method of .springframework.data.couchbase.core.convert.AbstractCouchbaseConverter

Code is shown below:

@Configuration
@EnableCouchbaseRepositories("my.repo.under.here")
public class EncryptionConfig extends AbstractCouchbaseConfiguration {

        // Usual Setup
        @Override public String getConnectionString() { return "localhost"; }
        @Override public String getUserName() { return "Administrator"; }
        @Override public String getPassword() { return "admin123"; }
        @Override public String getBucketName() { return "my_bucket"; }

        /* provide a cryptoManager */
        @Override
        protected CryptoManager cryptoManager() {
            try {
                // Load the Java KeyStore
                KeyStore keyStore = KeyStore.getInstance("JCEKS");
                FileInputStream keyStoreStream = new FileInputStream("/Users/asd1983/my-keystore.jceks");
                keyStore.load(keyStoreStream, "test123".toCharArray());

                // Initialize the Keyring with the KeyStore
                Keyring keyring = new KeyStoreKeyring(keyStore, alias -> "keypassword");

                // AES-256 authenticated with HMAC SHA-512. Requires a 64-byte key.
                AeadAes256CbcHmacSha512Provider provider = AeadAes256CbcHmacSha512Provider.builder().keyring(keyring).build();

                CryptoManager cryptoManager = DefaultCryptoManager.builder().decrypter(provider.decrypter())
                        .defaultEncrypter(provider.encrypterForKey("my-key")).build();

                return cryptoManager;
            } catch (Exception e) {
                throw new RuntimeException(e);
            }
    }
}

@Document
public class Data {
  @Id
  private String id;
  @Encrypted
  private String password;
}

package my.repo.under.here;

@Repository
public interface DataRepository extends CouchbaseRepository<Data, String> { }
