Caused by: java.lang.IllegalArgumentException: Attempt to execute an operation that requires a secondary index without defining the index attributes in the table metadata. Index name: gsiAuthorizationTable

Steps to Reproduce

The code is loading as part of Spring Boot application and connects to running locally DynamoDB. The application starts with the following relevant classes.

@Configuration
public class CustomerContext {

    @Bean
    @Primary
    public DynamoDbEnhancedClient enhancedDynamoDBClient() {
        return DynamoDbEnhancedClient.builder()
                .dynamoDbClient(dynamoDBClient())
                .build();
    }

    @Bean
    @Primary
    @SneakyThrows
    public DynamoDbClient dynamoDBClient() {
        return DynamoDbClient.builder()
                .endpointOverride(new URI("http://localhost:8000"))
                .region(Region.of("eu-west-1"))
                .build();
    }
}

@Getter
@Setter
@DynamoDbBean
public class Customer {
    private String primaryKey;
    private String sortKey;
    private String gsiPrimaryKey;
    private String gsiSortKey;
    private Instant created;

    @DynamoDbPartitionKey
    public String getPrimaryKey() {
        return this.primaryKey;
    }

    @DynamoDbSortKey
    public String getSortKey() {
        return this.sortKey;
    }

    @DynamoDbSecondaryPartitionKey(indexNames = "gsiAuthorizationTable")
    public String getGSIPrimaryKey() {
        return this.gsiPrimaryKey;
    }

    @DynamoDbSecondarySortKey(indexNames = "gsiAuthorizationTable")
    public String getGSISortKey() {
        return this.gsiSortKey;
    }
}

@Slf4j
@Getter
@Service
public class CustomerStoreDAO {
    private static final String TABLE_NAME = "customer_store";
    public static final String GSI = "gsiAuthorizationTable";

    private DynamoDbTable<Customer> customerStoreTable;

    private DynamoDbIndex<Customer> authorizationTable;

    public CustomerStoreDAO(CustomerContext customerContext, DynamoDbEnhancedClient dynamoDbEnhancedClient) {
        this.customerStoreTable = dynamoDbEnhancedClient.table(TABLE_NAME, TableSchema.fromBean(Customer.class));

        this.authorizationTable = customerStoreTable.index(GSI);
    }
}

Possible Solution

Context

The problem makes it impossible to work with GSI through DynamoDbEnhancedClient.

Sorry! This actually works fine.
The problem was with "get" accessor names which didn't match accessors generated by Lombok, so secondary key annotations didn't have any affect basically.
SOLVED.

If you also struggle with this: don't use fluent setters.
