CsvWriter not find eligible property

[cn-src]

simpleflatmapper.version:8.2.3

import lombok.Data;
import org.simpleflatmapper.map.annotation.Column;

@Data
public class GenGrid {
    @Column("gird_x")
    private int gridX;
    @Column("gird_y")
    private int gridY;
}

 CsvWriter<GenGrid> writer = CsvWriter.from(GenGrid.class)
                    .to(appendable);
            GenGrid value = new GenGrid();
            writer.append(value);

throw:

org.simpleflatmapper.map.MapperBuildingException: Could not find eligible property for 'grid_y'

sorry been late on that,
is there a setter or a constructor that set gridY? I assume lombok is doing that? could you send the .class generated for GenGrid?
also there no need for the @column annotation
