### Type Conversion
```java
import org.codelibs.core.convert.*;

// Safe type conversions with null handling

        if (response.isExists()) {

                option.converter(new EsTimestampConverter(), timestampFields).excludeWhitespace();
                option.exclude(OpenSearchAccessResult.ACCESS_RESULT_DATA);
            });
